Critical error after moving from Windows Host

[Mr. T]

Hi,

I'm pretty new to moving VM's and after looking around for information I feel pretty lost.

I'm trying to run a Windows Server 2008 guest on OSX 10.8.4. I've been running the guest on Windows 7. First I followed this post by mpack to transfer my VM to version 4. This worked just fine on my Windows host, but after moving the VM to my MBP i get critical error. By the way, a small difference between the hosts is USB support which I had to disable on the MBP.

I'm running VBOX 4.1.26 r84997 on both hosts. Log information is attached.

This error means something else is already using the virtualization feature of the CPU, and prevents Virtualbox from using it.

Thank you for your response, noteirak. Searched for the error and found ticket #10965. Installed both patches, which at first didn't seem to work, but restarted the computer and the VM started just fine:D Maybe a restart would've been enough...

I would advise upgrade to 4.2.x anyway, 4.1.x is becoming very old now and since 4.3.x is already in beta, not much support will come for 4.1.x I think.
