A critical error has occured while running the virutal machine

[GP]

Hi,

I need some help with this error on a clients computer.

When trying to start the virtual machine i get the message: A critical error has occurred while running the virtual machine and the machine execution has been stopped.

The host is is Windows 8 and the Virtual machine is xp.

I have attached the log and png file.

Any suggestions would be appreciated.

I believe this means that something else either is or has been using VT-x, and hasn't restored the CPU state properly. That would be another VM platform, or perhaps antivirus.

If the VM has a saved state then I would discard it, just in case this is due to changing hosts.

I checked the saved state and there was none.

I turned of the AV and still got an error message.

I think you are correct as the error message now says TV-x Setup Failed.

There is not other virtual software on the machine so I am not sure what could be causing it.

Any suggestions?

I just discovered the problem. After uninstall the Avast AV software the VM started with no errors.

thanks for the help.

After uninstall the Avast AV software the VM started with no errors.

I believe that Avast started using hardware acceleration for scanning purposes. I think that there is an option which disables that feature.
