Windows Virtual PC Beta on Windows 7
Windows 7 RC was released today on TechNet and MSDN along with Windows Virtual PC Beta for Windows 7. As soon as I started messing around with Virtual PC, I ran into a problem with an error message that said hardware assisted virtualization was not enabled.
This is a known issue with Windows Virtual PC Beta as described in the release notes:
“On computers that have an Intel® processor with Trusted Execution Technology (TXT) enabled in the BIOS, you may encounter an error message when starting a virtual machine, stating that hardware assisted virtualization (HAV) is not enabled, even though the HAV setting is actually ON in the BIOS.
Possible Workaround: Try turning off the TXT setting in the BIOS of the computer.“
The system that I’m using is a Dell Optiplex 755 with an Intel Core 2 Duo E6850 3.00Ghz processor which does have the Intel VT technology.
To fix this issue, I booted the computer and pressed F2 to enter the BIOS.
In the BIOS I verified the following settings:
- Security – Execute Disable (set to On)
- Performance – Virtualization (set to On)
- Performance – VT for Direct I/O Access (set to On)
- Performance – Trusted Execution (set to Off)
In my case Trusted Execution option was turned ON. So, I turned it OFF, Saved the BIOS settings and restarted the PC.
Windows Virtual PC Beta works like a champ now!
