I recently moved 3 VB instances (Turnkey Linux - Redmine, MediaWiki, and Nexus).

Moved From: Windows 7 - Desktop
Moved To: Windows Server 2008 - Dell Power Edge 2150

I had no issue with the instances before the migration. Now they all get random Guru Meditation screens, and hang. This happens at random anywhere between 1 minute, to a couple of days. It doesn't happen to each instance at the same time.

I attached the log.

The main warning that jumps out at me is:
"WARNING! 64-bit guest type selected but the host CPU does NOT support HW virtualization." But I haven't figured out yet if there is a way to resolve this, or if this is the root cause of the problem.

64-bit guests need hardware virtualization enabled in the host's BIOS (which means that you have to enable VT-x/AMD-V in your BIOS). Look at your user-manual for your specific model on how to do this.
When creating the 64-bit guest VM you must select 64-bit variant of the OS (VM Settings -> General -> Basic -> Version).
If another virtualization program is running and not "cooperating" you must disable it or uninstall it (see example below).
If running Windows as host you must make sure Hyper-V or XP-mode is not enabled on the host.

Thanks. I will have my server admin see if he can modify these bios parameters.

That seems to have worked. The virtual boxes have not crashed for two weeks. Thanks!
