I had the bright idea to install Windows XP Mode in order to try to solve this problem from yesterday. It seemed to work nicely, but as part of the new Virtual PC and Windows XP Mode installation, I had to enable the Intel virtualization support in my BIOS. With it enabled, I could use XP Mode just fine. However, when I tried to start my VMware VMs which existed prior to my installation of XP Mode, the VMware VMs failed to start. Instead, VMware Workstation (6.5.2) gave me a discouraging error message. This message is from the log file, but the UI gave this in a messagebox also:

Msg_Post: Error

Oct 01 08:39:12.852: vcpu-0| [msg.panic.response] We will respond on the basis of your support entitlement.

This error message seems to be reversible. I can turn on hardware virtualization and get the error. I can turn off hardware virtualization and get the VM to boot up just fine. Rinse, repeat. If this is just a coincidence, it's a strange one.

So, is there any way I can get my VMware VM to run correctly with the BIOS virtualization switch turned on? I'd really like to be able to use both VMware and XP Mode, if possible.

You can have both and also make use of VT-x but you can't run them both at the same time.

Take a look here:

The post above corresponds with my findings.

I think you can only run VMware xor Windows Virtual PC (which is what XP Mode is, I think).

The two don't go together. I think it has nothing to do with you switching on Intel VT-x support. XP Mode requires it, VMware should run with or without VT-x.

So are you suggesting that my problem might be that the Windows virtualization stuff is starting up early on my machine when I have the VT-x enabled, and that is what is keeping my VMware stuff from working? – Chris Farmer Oct 1 '09 at 14:12
