In October, when Apple introduced a change in policy allowing Leopard Server to run in a virtual environment on Apple hardware, Mac IT geeks everywhere looked forward to the day that they could run Windows Server, Linux and OS X Server all off their pretty Xserves. That day is today, because Parallels Server for Mac is now out of beta!

According to Parallels, this is the "...first server virtualization software to run on Intel-based Xserves...and to power VMs running on the Mac OS X platform." Similar the the Parallels Desktop product, Parallels Server lets you run virtual instances of different operating systems on top of OS X Leopard Server, including Leopard Server. The next beta of VMWare's Fusion, which like Parallels Desktop is a consumer product, will support Leopard virtualization as well, but Parallels Server is a little different and aimed at a different market.

The difference is that the hypervisor used in Parallels Server is hardware optimized and takes advantage of Intel's VT-x acceleration (which new XServe and Mac Pros have) to provide a more robust experience with better allocation of resources and memory. This makes the experience much more akin to running a completely separate machine, as opposed to running one OS on top of another.

Yesterday, we reported on Media Temple's new (xv) project, which is the first official service that will be run on Xserves running Parallels Server for Mac. The (xv) will be running multiple VMs of Leopard Server, but Parallels Server can also support Linux (Debian, SUSE, Red Hat and Ubuntu), Windows (Server 2008, Vista, XP and Server 2003 and Windows 2000) and FreeBSD 6 and 7 as guest OSes. So if you run your website off of CentOS (which is based off of Red Hat Enterprise) but your company network runs off of Leopard Server, you can do both off of one Xserve.

Make no mistake, this is an enterprise product, and as such, it is pricey. Parallels Server for Mac is $1248.75 for the software and one-year of support and maintenance and that's before you add in the cost of any software licenses you might need, but that's still a lot less expensive than another Xserve.

For enterprise users who are interested in virtualization, definitely check out the free trial.

Thanks Russ!

Teaming with Parallels, Media Temple has just announced the start of private-beta period for its latest (mt) Labs offering, the (xv) Xserve-Virtual -- which they are dubbing "the world's first VPS Leopard Server." Although virtual servers running Linux or Windows are pretty standard hosting options, this is one of the first Mac hosting opportunities I have seen period (outside of a co-lo), virtualized or not.

Now that Apple has sanctioned the virtualization of OS X Leopard Sever on Apple hardware, both Parallels and VMWare have announced plans to integrate Leopard Server virtualization into their product lines. While VMWare is integrating Leopard Server in its upcoming version of Fusion, Parallels is taking a decidedly more enterprise approach and working Leopard Server virtualization into its Parallels Server product. Parallels Server uses Parallels' bare-metal hypervisor architecture and as such, each virtual machine runs its own kernel and operating system.

Media Temple, which already partners with Parallels in its (dv) and (dpv) Nitro products, is going to be the first official hosting launch partner for Parallels Server for Mac, offering Leopard VPS hosting on Xserve hardware. The Xserves used by (mt) are running 2 x 2.8 Ghz Quad-Core Intel Xeon 5400s with 32GB 800MHz DDR2 RAM and 3x300GB 15,000-rpm SAS with 16MB disk cache drives on a Xserve RAID Card. In the private beta (apply here), the Xserves will be split into 8 virtual machines, with each VM guaranteed 2 GB of RAM and two cores of CPU resources. The advantage of using a virtual machine as opposed to a physical Xserve, aside from cost, is that hardware maintainance is taken care of by the host. Plus, if something goes completely haywire, the virtual machine can just be reinstalled to its starting point.

The (xv) can be used to host websites, run iChat and iCal server, use Podcast Producer and for anything else a regular Xserve running on a LAN can do. Anything you can install on a regular Mac, you can install on the (xv), and you can control the (xv) using both Screen Sharing and Remote Desktop. Media Temple is still working on the scalability plans for the (xv) but are planning on offering a scale-on-demand package similar to its (dv) product.

Although pricing is currently undetermined, Media Temple will be using the beta testing to find out which configurations are most efficient to help set the ultimate price.

If you have experience running a Mac server, you can apply for the (xv) beta here. It's really exciting to see OS X virtualization, both for enterprise and for home/small business use take off. I can't wait to see the final product!

Thanks Jen and Jorge!

It's the Holy Grail of Mac virtualization: a Mac inside another computer, running happily on a virtual machine and subject to your every whim. Up until last fall, there was no framework in Apple's licensing to allow for Mac OS X virtualization; then the ground shifted and the heavens shook, and there was a way forward. Mac OS X Server is now eligible for virtualization on Apple hardware, so naturally both big Mac virtual machine players are eagerly pushing forward on this front.

Parallels is offering OS X Server virtualization as part of its Parallels Server high-end product, which is currently approaching the end of its beta; the gang at VMware, however, are going the route of integrating OS X Server virtualization into the consumer level Fusion product. VMware has announced that the next beta of Fusion 2 (and the eventual release) will include the option to virtualize Mac OS X Server. This is awesome news for anyone using Fusion now, as the upgrade to 2.0 is free for existing customers.

Of course, virtualizing Mac OS X Server is not an inexpensive proposition, as even a 10-user license of Server clocks in at a cool $499. For developers and corporate folk, however (many who would have access to volume or seeding licenses of Server), it's a great help. Video demo of VMware's new feature announcement after the jump.

Thanks Peter.

We first noted the open-source virtualization application VirtualBox way back in 2007, and since then this open-source competitor to VMware Fusion and Parallels has come a long way. Most importantly, perhaps, the project was acquired by Sun Microsystems and has now become Sun xVM VirtualBox with a great deal more support.

The application is free for personal use and is available for a wide variety of x86 platforms including OS X on Intel Macs. The feature set is extensive and includes a lot of the features of its commercial counterparts. That said, it lacks many of the niceties of those programs, including any kind of 3D graphics support. Nonetheless, it's hard to argue with free and is probably worth checking out if your virtualized Windows requirements are modest.

Sun xVM VirtualBox is a free download from Sun.

Thanks, Dean!

Over on the blog for VMware Fusion, they've announced the release of version 1.1.2 which adds support for Time Machine backups of your virtual machines. Apparently 10.5.2 fixed some problem that prevented virtual machines from being backed up properly and they have now enabled it. They warn, however, that since Time Machine backs up anything that changes, and virtual machines tend to be rather large, you may want to exclude certain virtual machines to avoid losing too much space on your backup drive.

The new version also adds support for the MacBook Air (fixing a problem with the virtual drive), Windows XP SP3 Boot Camp partitions, and simplified Chinese, as well as quashing various bugs.

VMware Fusion 1.1.2 is a free update for registered users and $79.99 otherwise.

Thanks to everyone who sent this in!

We posted about the release of CrossOver Games a little while ago -- it's a version of Codeweavers' Windows virtualization software that allows Windows games to be played on OS X and Linux. I grabbed a copy of the software for TUAW, and spent an afternoon running it through its paces.

You can check out the hands-on after the break -- after installing CrossOver Games, I first tried to load up Guild Wars using their installer's package interface, and was able to get it working pretty well. I then tried one of my favorite games, Civilization 4, and unfortunately, that one didn't turn out quite so well. And just for kicks, I also gave F.E.A.R. a shot -- it's not on CrossOver's compatibility list at all, but I've had a copy sitting around for a while that I haven't played yet, so I let the virtualization app take a crack at getting it working.

The hands-on is in this simple and easy-to-use (which is more than I can say about CrossOver Games) gallery format -- just click the picture furthest to the left down there and begin our journey into the exciting world of virtualization and game installation. I can tell you're excited already.



Update: Arjun found the problem with Civ in the comments; apparently only the Steam version is compatible. Which vibes with the rest of what I found: if you want to play any of the Steam or built-in games with CrossOver, they'll likely work just fine. But if you want to install another game from a CD (especially unsupported games), you're out of luck.

Despite the publicity around Parallels' flagship Mac product, Parallels Desktop (which we've contributed to in some small part), there are some other interesting tools in the stable of Parallels' parent company, SWsoft -- which is now being rebranded as Parallels, Inc. just to keep us on our toes. One of those products is Parallels Virtuozzo Containers (PVC), which launches version 4.0 today in a webcast event at 11 am (Eastern). While PVC is not a Mac-compatible server (yet), the technology choices Parallels made in developing it may illuminate some future paths for the yet-unreleased Parallels Server product for Mac OS X.

Virtualization products like Parallels Desktop, VMware Fusion, and Microsoft's Virtual Server work via a hypervisor model, virtualizing the hardware platform so that each virtual machine runs in its own full-OS environment. This approach does a great job of insulating the VMs from the underlying physical hardware and provides for OS and build diversity (Windows, Linux and eventually Mac OS X Server running on the same virtualization platform) but it has some drawbacks: each virtual machine consumes a full helping of RAM, disk space and CPU resources while running, as though it was a physical machine. VMware in particular is respected for its expertise in optimizing these resource demands with its ESX enterprise-level server products, but the baseline requirements for system resources can't be fully alleviated.

PVC does OS virtualization, which tackles the problem of resource allocation for virtual machines in a different way. Virtuozzo VMs, or "containers," are created as overlays on the base OS that runs on the physical server, like a piece of transparent acetate over an animation backdrop. All the basic OS processes, files and libraries are present in the base server OS instance, and the container holds the differential changes that allow the VMs their individual characteristics and configurations. While you sacrifice one big feature of hypervisor systems, the ability to diversify OSes -- since the base OS is fixed as either Windows or Linux, all the containers have to be built on top of that OS -- what you gain is substantial, as each additional running VM takes only a small chunk of RAM and a comparatively tiny swath of hard drive space to work in. Virtuozzo servers can handle high VM loading on relatively modest hardware without taking major performance hits, which is a big plus if your server budget is constrained.

In the OS X virtualization session at Macworld Expo, the Parallels folks suggested that we may see both hypervisor and OS virtualization approaches integrated in the Parallels Server product, as the engineering teams from PVC and Server have the opportunity to put their heads together. Parallels has also said that the management tools for PVC and Parallels Server will be integrated as development moves forward. Even though PVC doesn't support the Mac directly, if you're interested in virtualization you might pop into the webcast and check it out.

Although I am, and always will be, a devoted user of Apple products, the Macintosh and OSX, occasionally I find the need to do something that only the vagaries of Windows can accomplish. In the past, this required me to have a separate computer (a PC) with an install of Windows.

Fortunately, with Apple's switch to all Intel all the time, I no longer need that other Windows PC and instead can use a "virtual" Windows PC running on my Mac with the help of a software product provided by Parallels or VMware.

In the past, I was a big fan of Parallels and used it exclusively. More recently, though, I have switched to VMware Fusion for my Windows virtualization needs. Nothing against Parallels, its still a great product, but I just find VMware a bit more "Mac-like" and easier to setup and use. If you agree and use VMware Fusion as well, head on over to their website because there's an update to the software waiting there just for you.

This update is, according to the VMware site: "a maintenance release that contains fixes for a variety of issues." What might these issues be, you may wonder? Well, if you really want to know, feel free to read the release notes. Or, if you decide to just "go for it" and not read the fine print, go here and download away.

Earlier this week we gave Parallels a turn, and today it's VMWare in the spotlight. Scott spoke to Pat Lee, senior product manager for VMWare, about Fusion, virtualizing Leopard server, upgrading from VirtualPC (there's now an importer for VirtualPC 7) and more.

While VMware's OS X virtualization offering is described as a 'technology preview' (translation: still too buggy for beta), the team at Parallels is beta-ready with the new Parallels Server product, allowing you to virtualize OS X Server alongside your Windows, Windows Server and Linux VMs. The server version from 'Big Red' also features experimental support for Intel's VT-d directed I/O capability (present on the newest Mac Pro and XServe machines), lightweight and 'bare metal/headless' hypervisor modes, and 2-way SMP multicore in a VM (expected to support 4-way SMP in the final version).

Feel the power of this mostly operational virtualization station in our brief video demo with Parallels marketing lead Ben Rudolph (video after the jump). Pricing and availability on Parallels Server aren't announced yet but as soon as they are we'll let you know.

Update: Commenters have suggested that 'too buggy for beta' was an unfair characterization of VMware's demo, and they're probably right -- I did not mean to diminish the incredible efforts of developers at VMware, who like the Parallels crew have been working very hard on this. Also suggested was the notion that Parallels Server beta is an inferior offering and it can't install an unmodified copy of Leopard Server (as VMware's demo did -- the video linked on Regis' blog was shot by me :-). I can't vouch for the install process, but I can say that the Parallels instance of X Server worked as expected when I had hands-on time with it. Parallels is not new, corporately, to the challenge of enterprise virtualization; the Virtuozzo product line is both reliable and well-regarded, and the engineering talent behind those products is now collaborating on the Parallels Server work.

The long history of the Parallels Server release is moving ever closer to an end: SWsoft (which is changing their name to Parallels) has announced that the product has moved into beta. This thing is the holy grail for Mac server administrators, apparently-- it's supposed to not only be the first virtualization solution to run on Apple hardware, but will also allow admins to run multiple versions of Leopard on one box, and even on Windows or Linux servers. I'm pretty clueless at fine art of administering servers, but even I can see how that would have all the IT guys in a tizzy.

It's still a closed beta at this point, so you've got to sign up if you want to experience the magic for yourself. And apparently the Parallels folks work fast, so odds are we're headed for an open beta within a few weeks. Soon, Mac OS Server will be at the mercy of any IT overseers to bend and use at their will.

MacWindows reports that CrossOver (which was already doing pretty well with Windows games inside OS X) is planning to release a gaming-optimized version of their virtualization software. It'll be called CrossOver Gaming, and while we're not actually given details of how it's going to be "optimized" for games, we are told that it will be compatible with more Windows games than ever before.

Additionally, the new version will actually be a subscription model-- instead of just buying the software, you'll pay $5 a month (presumably for quick updates on brand new games). Other than that, we're not quite sure what advantage CrossOver's system will have over, say, running games in Windows via Boot Camp (seems to me that if you have the hardware to run Windows games, you have the hardware to run Windows and games at the same time), but we'll have to see-- CrossOver says the new Gaming version is due sometime later this year.

Like it or not, lots of us who own Intel-based Macs have to run Windows from time to time. Although Boot Camp is pretty fantastic if you need to run a processor intensive application (or you want to play games), virtualization is the more attractive solution for users who need to access productivity applications, like Microsoft Office 2007, but don't want to have to live in the Windows environment. The two big players in the virtualization field are VMWare's Fusion and Parallels' Parallels. Both applications let you install a Windows XP or Vista virtual machine on your Intel Mac without having to leave OS X, both offer a level of integration between the two operating systems and both retai for $79.99 (USD). So, which virtualization program is the fastest? Well, that's what MacTech attempted to find out in their exhaustive benchmarking trials, comparing Fusion 1.0 (build 51348), Parallels 3.0 (build 5160) and Boot Camp head-to-head-to-head in a variety of different computing tasks.

So what's the bottom line? Because of how the software if designed to integrate between the two platforms, Parallels came out ahead in many of MacTech's tests. For certain more processor heavy uses, VMWare, thanks to its ability to take advantage of both cores, came out the best. For networking performance, Boot Camp was king.

While I found the benchmarking tests very interesting - and useful - prospective buyers should be aware that in the middle of MacTech's testing procedure, all three Windows options for OS X were upgraded. With the release of Leopard, Boot Camp came out of beta and VMWare is now at version 1.1 and Parallels was updated on December 5 to build 5582. I know just from my own unscientific experience, Fusion 1.1 improved significantly in speed and overall performance from version 1.0 and while I was a big fan of Parallels under Tiger, I have "switched" to Fusion for Leopard.

Trial-versions are available for both programs. Remember that in order to use Windows XP or Vista, you need a valid user license.

Thanks, Rich.

In our post yesterday on VMware Fusion 1.1 we mentioned that VMware had also included a beta of their new Importer application. However, after using it tonight, I thought it was worth a separate post of its own, because it makes migrating from Parallels to Fusion incredibly easy. The amazing thing is that I converted an old Parallels 2.5 WinXP VM which Parallel's 3 itself had not been able to import successfully!

Basically, when you start the Importer it gives you a window in which to drop the Parallels .pvs file (just Win2000, WinXP, Win2003 Server or Vista at this time). It asks you where you want to save the new Virtual Machine and a few minutes later, boom it starts right up in Fusion -- no muss and no fuss. For me the amazing thing was that I had previously tried to import the same image into Parallels 3 and it failed. So basically the upshot is this: if you're running Parallels, but you'd like to give Fusion a try, the barrier to entry has now dropped to next to nothing (besides the hard drive space).

I bought Parallels for my Intel Mac as soon as it was released,but given my experience with Fusion (especially with the downloadable appliances), I think VMware has a convert. I fully recommend giving it a try. The VMware Importer is a free download. It's also supplemented by the VMware convertor which will create an image of a working PC that can then be imported into Fusion as a VM.

Even though Leopard ships with Boot Camp, lots of Mac users still get their virtual groove on with VMware Fusion, and its super-slick window display tool Unity. Today VMware announced Fusion 1.1, an upgrade that sports some cool new features and improvements:

• As expected, the upgrade now supports Leopard

• Better 3D graphics via the "experimental support" for DirectX 9.0
  

• Full Vista and XP support

• A beta version of VMware Importer, a tool that allows users to quickly import virtual machines (including Boot Camp)
  

• Overall better speed and performance

All told, there are about 25 enhancements in Fusion 1.1. Pat Lee, VMware's senior product manager for Mac products, told me that this upgrade is "all about giving the user choice." He points out that the biggest advantage of Fusion over Boot Camp is the ability to access your Windows virtual machine on the fly.

Lee says that, unlike Boot Camp, it's not necessary to shut down your Mac and reboot into Windows every time you want to get to a Windows app. Instead, just use the Unity tool to co-mingle your Windows and Mac apps right on the same screen.

On the other hand, if dual-booting is your thing, you can always use Importer to create a virtual machine.

The upgrade is free for existing customers. If you're ready to try it out for the first time, snag a free 30-day evaluation from the company Web site or purchase it for $59.99 with a $20 rebate (US only).
