My 3 rules for improving perf.
1. Add more RAM
2. Add more RAM
3. If there are any empty memory sockets , add RAM.

With XP mode it is always a compromise because adding memory to the VM takes it away from the host. So you need to balance VM performance against host performance.

The other thing which will make a difference is the type of virtual hard disk you use. By default XP-Mode creates differencing disk for each XP VM , a differencing disk is slower than a single disk, and if you have a single disk a Fixed disk is better quicker on writes than the a dynamically expanding disk .

Then the speed of the disk has an impact.
I'm a systems admin for a living with a considerable amount of experience with virtual machines...both stand-alone applications as well as hypervisor based products.

My only complaint with Windows XP Mode...is that it's terribly slow compared to other 3rd party products. While I understand where you are coming from with more RAM and faster hard drives...these aren't really necessary with the 3rd party products.
Are you talking about Virtual PC, or when you use applications from (XP/Win 7 etc) virtualized into the host environment?

You can have a look at this other thread to get the main point that I am making
XP Mode is slow--any way to improve

In a nutshell, the XP Mode while easy to install and use...but is considerably slower to boot and launch applications than running XP installed under VMWare Player 3.0 or Sun VirtualBox 3.x

Originally, I was very bummed because I wanted to make use of the activated copy of XP that I was entitled to when I purchased Windows 7 Ultimate. However, since that time, VMWare Player 3.0 has introduced the ability to convert that instance and use within VMWare Player 3.0 without violating the MS EULA...so I got what I wanted in the end.

Yes. I too found that XP Mode is slower than others such as VMWare and VirtualBox.

Can VMWare Player 3.0 and Windows Virtual PC co-exist on the same machine?

You can have VMWare, Sun VirtulaBox and Virtual PC installed on the same machine at the same time, but you can only have one of those running on any given moment. When I want to run Mandriva Linux which I have installed on VirtualBox, I have to first shut down Virtual PC and XP Mode

Yeah, I tried running XP Mode and VirtualBox but a nasty error came up.

I enjoyed this Q & A with the MS people. We should shoot for that again for another topic or topics.

OK, so I just now tried to get into my Virtual PC/XP Mode and got this error when clicking the "Windows XP Mode" icon...

Post your questions to the MSFT Virtualization team-virtual-machine-error.jpg

Anybody know what's going on here. I haven't made any changes to the machine since installing it. And it initially worked, as I was posting about it here. Now for some odd reason it doesn't

If I click on the "Windows Virtual PC" icon, it takes me here.... C:\Users\MyName\Virtual Machines

Post your questions to the MSFT Virtualization team-xp-mode-location.jpg

...and clicking that link (windows xp mode.vmcx) gives the same error...

I'm thinking about doing a reinstall. However when I did attempt to do the uninstall, I was warned that the files on the VHD will also be removed. So I’d like to try going around that first.

Again, don’t know why the error since I’ve made no changes to the machine since installing the program.

Any suggestions on a fix?

Thanks.

This has happened two times to me. Only workaround I've found is to create a new virtual machine using your existing XP Mode vhd-file.

Goes like this:
  • Open C:\Users\Your_Username\Virtual Machines, click Create virtual machine
  • Name the new vm, click Next
    Post your questions to the MSFT Virtualization team-xpm_new.png
  • Specify amount of RAM you want to assign to this vm, click Next
  • Choose Use an existing virtual hard disk
  • Click Browse, choose the existing XPM vhd (default location C:\Users\Your_Username\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines\Windows XP Mode.vhd)
    Post your questions to the MSFT Virtualization team-xpm_new2.png
  • Click Create
  • Test your new XP Mode. If it starts and runs, you can now delete the old XP Mode by removing following files:
    • Windows XP Mode.vhd
    • Windows XP Mode.vmc
    • Windows XP Mode.vmc.vpcbackup
    • Windows XP Mode.vsv (exists only if vhd was hibernated)
      The above mentioned files are located in C:\Users\Your_Username\AppData\Local\Microsoft\Windows Virtual PC\Virtual Machines
    • Windows XP Mode.vmcx in C:\Users\Your_Username\Virtual Machines

This has worked for me.

How is Parallels virtualization different from normal virtualization?
I started thinking about our computers.. why we cannot run two operating systems on the same computer at the same time - without virtualization. We have plenty of Ram these days and often 2 or 4 Central Processing Units. Surely someone could come up with a way to make this work. So I started...

CAUTION!<---Make sure MSFT doesn't GIVE you TWO KEYS!=MSFT=wasteful
I just realized that once you get a key and click on DOWNLOAD, MSFT gives you yet ANOTHER KEY and of course it will work (all the keys work, 32 works for 64, 64 works for 32, et-cetera), this means MSFT is being wasteful and we will ALL be getting 2 keys. Make sure when you click on DOWNLOAD,...
