I'd like to use alternatives to System Center Virtual Machine Manager 2008 is possible, in other words, any FREE tools?
Before SCVMM, Microsoft's solution was the Virtual Server Migration Toolkit. This requires Windows Server 2003 Automated Deployment Services, which in turn can only be installed on Windows Server 2003 Enterprise Edition. It's about as far from a free tool as you can get. It only works on SP1, not SP2 (unless ADS has been updated since I last checked), and you have to obtain all the patches you've applied to the physical system.
ADS is limited to four partitions per physical disk, because it can't create extended partitions. If your physical system has more than four partitions you have a problem.
Once you do have it running, though, it does actually work.
Many disk copying tools like Ghost or True Image can now produce .vhd files from a physical system.
Google "Pysical to virtual conversion" or P2V. There are several solutions available. Unfortunately it sounds as though not many have had success with Microsoft's solution.
Try the following:
1. Download and install the VMWare Converter and follow the instructions to convert the physical machine.
2. Download the VMWare to VHD conversion utility from VMToolkit.com and convert the image.
This didn't work for me when I tried it last week, but I think it is because the drive I converted used PGP.
Use VMWare its not free, but you can get a decent 30 day trial, which should be enough to do your conversions. VMWare also has other great advantages if you're willing to pay for the product.
First, backup the physical system to an image, and convert it to a virtual disk which can be directly used in a virtual machine.

I want to install TFS 2010 on my own machine - a Dell Laptop with 8GB RAM, running Windows 7. Now, since installing on Win7 means I can't run SharePoint or Reports, and I don't want to reformat my machine to Win 2008, I need to virtualize.
I would like something that I can have always on, and treat like a server on my LAN, or at the very least, something that I can activate quickly, when needed. Oh, and I'd like it to be free :).
As far as I can tell, my options are MS Virtual PC, Virtual Box, VMWare.
What would be my best option? Are there any other options?
Thanks,
Assaf
You can either use MS Virtual PC or VMWare. I have been using TFS2010 installed on MS Virtual PC and its working fine.
If you want to use 8 GB RAM, you'll want to use either VMWare or repave your machine (but save the TFS databases) as Windows Server 2008 R2 and use Hyper-V.
You can then install TFS 2010 again but point it at your set of restored databases. You'll be able to enable the SharePoint and Reporting for your newly restored TFS instance.
I've ran it on a VM from my Dev box and the performance wasn't the best. Memory and disk IO are very important when running SQL and the competition with multiple instances of Visual Studio, plus the overhead of VMWare made it unbearable. With enough memory and RAID or a SSD, you may be okay.
I know it's not free, but there are a few hosted solutions that are decently priced (TFS Server Hosting). They also allow you to access it from anywhere and your code will be backed up.
I want to clone a AIX LPAR and was wondering if the physical machine could be converted into a VM Image?
I have used the VMWare Converter to create a VM Image of a physical windows box and the documentation states that you can do that for Linux Boxes too.
http://www.vmware.com/products/converter/
I don't see information on AIX or the other UNIXes.
If creating an VM Image of an existing physical AIX box is not feasible is there any easy way to clone the AIX image to another AIX machine.
The primary intent is to avoid re-creating the setup that is already performed for the current AIX box and we want a duplicate environment with the same setup.
VMware supports x86 (and x86_64) architectures for host and guest only. IBM AIX runs on the Power architecture, and VMWare does not do architecture emulation, so what you want does not exist.
If you want to back up/clone your AIX instance to another machine, look for information regarding mksysb and AIX Sysback.
You might want to take a look at the following, but there are no guarantees, and I'm fairly certain running AIX on anything but a Power architecture is still not a reality at this time:
Qemu
PearPC
Based on further reading, i understand that VMWare does not support AIX. The guest OS can primarily be Windows, various distros of LINUX and Mac-OSX. I also see Solaris as a supported guest OS, but i don't see AIX. So i don't think this is possible.
I would have to look at the Virtualization features supported from IBM for this activity.

I was wondering if there was a very simple and free virtual machine that would allow you to boot from a folder or disk image that couldn't damage my hard disk. I am using a MacBook and am looking into operating system programming. I found a tutorial on the internet that looked promising. I want to try this but using a VM instead of actually booting from a disk. If I made a folder or disk image containing the boot.bin file and wanted to try the OS I made (while booting from a folder or disk image, not a disk), is there a VM that would let me do it? I have no previous experience with virtual machines. I also want to be sure my hard disk would not be damaged.
If you can make a cdfs .ISO, any VM technology on the market today could do what you ask. VirtualBox, KVM, Xen, VMware, VMware Fusion (on the macbook), etc. Not sure if Parallels can work for you, though.
VMware's products can also boot from floppy images, which are simply binary blobs (for the most part).
On the Mac I think you're limited to VMware Fusion (maybe Parallels), but on Linux you have so many options.
virtualbox (formerly from Sun, now from Oracle) is probably the most powerful VM that you can run on all of Windows, Macs and Linux (OpenSolaris too of course;-) and is at the same time open source (and, of course, also free as in free beer). Whether it supports your new OS is not entirely certain (since it's oriented to supporting a specific list of "guest OS"s and of course your new one isn't there), but, what with it being free, it's surely worth giving it a try.
Can I really do this?
As I am reading up on virtualization, I am getting more excited. The latest thing I am realizing, that it may actually be possible to take my existing XP Pro development workstation(VS 2005/vs2008/sql server etc) and simply convert the entire installation to a virtual image and load onto my new box? Sounds to good to be true? Does it really work that easy? If I can take a complete "dump" of a machine and simply move it onto my new workstation, not even need to find all my old install disks, that is truly amazing.
Does one of the VM products support this better than others? that may tip the scales for me to pick one platform over another..
How is it that I have not gotten onto this VM bandwagon sooner!?
Edit/Update: Just as a quick update in case anyone is interest. Got the machine, decided to go with vmware and had a heck of a battle, first trying to figure out which product to use, and then actually getting anything to work. The instructions are not obvious and wasted my 6 hours trying to a) get a vmware working, and b) actually trying to do a conversion of my old XP machine into a VM - never got it working.
In frustration I downloaded MS Virtual PC in minutes, had it up and running in 5 minutes, and was creating VM's within the hour....VERY easy. I haven't however figured out how to convert my old XP machine into a VM - but, now having a VM running, it seems obvious to me that I wouldn't want to actually run a primary development setup in my VW window anyway.
Definitely VMware Converter.
VMware Workstation is the most user friendly and fully-featured app that I've used and is well suited for debugging. Check out an awesome video demo of the record/replay feature here.
VMWare has p2v. By far the easiest solution you could take, and it's pretty easy to convert the VMDK into a VHD if you want to use a different solution.
Three options I have used.
1) Vmware convertor will create an image for you you can move around forever. You can then run it for free in the VMWare player.
I think the easiest thing would be to connect an external drive to your computer, convert a computer into an image onto that drive, plug the drive into another machine, and try it out..
2) Ghost is ghost.. You can use something like norton ghost or a linux equivalent to mirror the drive onto a larger one. If you have driver issues you can do an inplace re-install over the existing xp install and it will replace the drivers and leave all your applications, data, and settings intact.
3) Go Mac. They're strange. You can link two macs up with a firewire cord and it will copy over your entire setup, including virtual machines. I have my laptop backed up and if it dies, I can transfer the identical computer onto another one in minutes as all the internal components in Apple are intel and the drivers are one and the same.
Options I've heard of:
4) Microsoft Virtual PC. A fourth option that I have been hearing good things about is Microsoft Virtual PC. They bought the technology from another company and
5) Citrix - This one is intriguing because it would conceivably work as well, if not better than VMware. At least that's what I hear from my Citrix friend.
Welcome to the club of virtualisation. I set up a virtual machine on my Vista Os and running xp simultaneously. Its great as some apps don't work in 64bit (ie. those old 16bit apps.). You can try Microsoft Virtual PC 2007 its most probably the most user friendly. It's what I use. You can try Virtualbox too.
You can set up a partition and allocate space to the new operating system for this to work. Or use a spare formatted secondary drive if you have one.
Best of luck!
We now do all development in VM's.
The desktops are locked down tight and out IT manager is happy.
We use VirtualBox and it's fine.
There are fairly clear instruction for using physical disks directly for VirtualBox anyway.
The P->V transofer is not terribly hard.
Can't say the same of MS VPC or VMWare.
Here's a link to XenConvert, which is specifically designed for this "P2V" (Physical to Virtual) conversion, to show that the answer to your first question is "yes", it can be done.
http://www.citrix.com/site/ss/downloads/details.asp?downloadId=2318170&productId=683148
However, that tool is designed for stuffing your XP machine's image into a server, rather than onto your desktop machine.
For your more specific problem of doing this for your desktop, you're talking more about "Client Virtualization" (as opposed to Server Virtualization), where tools like XenClient, KVM, Virtual Box, qemu, Parallels, VMWare Workstation, etc. are better suited, and each will have their own P2V conversion technique.
I am using VMware Server 1.0.7 on Windows XP SP3 at the moment to test software in virtual machines.
I have also tried Microsoft Virtual PC (do not remeber the version, could be 2004 or 2007) and VMware was way faster at the time.
I have heard of Parallels and VirtualBox but I did not have the time to try them out. Anybody has some benchmarks how fast is each of them (or some other)?
I searched for benchmarks on the web, but found nothing useful.
I am looking primarily for free software, but if it is really better than free ones I would pay for it.
Also, if you are using (or know of) a good virtualization software but have no benchmarks for it, please let me know.
From my experience of Parallels and VMware (on the PC and more extensively on the Mac) the difference between any 2 competing versions of the software is usually quite small and often 'reversed' in the next releases.
I never found Parallels to be much faster (or slower) than VMware - it often would be a case of the state of the VM I was running, the host machine itself and the app(s) I was running within the VM. If VMWare brought out a new release which did something faster, you could be sure that Parallels would improve their performance in that area in the next release, too.
In the end I settled on VMWare Fusion and the key reason for this was just that it played nicely with VMware Workstation on the PC. I have trouble taking Parallels VMs from the Mac to the PC and back again, and this worked fine on VMware. Finally, though this is less of a concern, I was unhappy that sometimes it felt as if Parallels would release a version without proper regression testing - you'd get the up-to-date version and find that networking was suddenly unexplicably broken until they released another patch a few days later. I doubt this is still the case but VMware always felt a little more 'in control' and professional to me.
I'd go for a solution that you can get running in a stable fashion on your PC, that is compatible with your other requirements (such as your co-workers' platforms and your overall budget). You can waste your lifetime trying to measure which one is faster at any given task!
One other thing - it's worth checking the documentation that comes with the software, and any forums etc, before making judgements about performance. For instance, in my experience throwing huge amounts of ram at your VM (at the expense of free ram in the host system) does NOT automatically make it faster; better to split the ram up evenly, and certainly keep an eye on any recommended figure. In VMware, that recommended figure is a good guide.
You'll get best performance if your hardware supports hardware virtualization, such as AMD's AMD-V or Intel's VT, and you enable this feature on the computer and in your virtualization software.
For Microsoft solutions, you need at least Virtual PC 2007 or Virtual Server 2005 R2 SP1, or Hyper-V on Windows Server 2008 (I don't expect you'll rebuild your system just to run Hyper-V, but I thought I'd mention it).
Subjectively I haven't noticed any difference between Virtual PC and VMware Workstation performance; I'm using VMware now as it supports USB virtualization, which Virtual PC doesn't.
You also generally need to install appropriate custom, virtualization-aware, drivers in the guest OS, as the standard drivers are expecting to talk to real hardware. In Virtual PC and Server these are called Additions, in VMware they are VMware Tools.
Anandtech has some great info on virtualization. Although they are not any benchmarks, it provides a great insight on why it is so difficult to do proper virtualization benchmarks. I cannot suggest you a specific product, because it depends very much on your requirements.
