I was wondering if anyone has encountered a similar problem described below.
This is 100% reproducible for me.
Intel Core2 Duo E8400.
Gigabyte EP45T-U3DP with latest BIOS.
Virtualization extension enabled in BIOS.
Ubuntu 10.04 64-bit host
OS (2.6.32-21-generic #32-Ubuntu SMP)
Virtualbox 3.1.6 (downloaded from virtualbox.org)
Windows XP Pro 32-bit guest OS
The virtual machine can be started with VT-x/AMD-V without any problem when the host
is freshly booted. If the host
is suspended (S3 suspend
to RAM) and subsequently resumed, then Virtualbox will completely freeze the host
if I attempt to start any virtual machine. If VT-x/AMD-V is disabled, then the virtual machine will run and won't freeze the host
(Display 2D/3D acceleration setting does not appear to have any effect on freezing)
Same freezing occurs when VMplayer is run.
There is a ticket 5048 that describes the same problem (http://www.virtualbox.org/ticket/5048
), but I don't understand the resolution
Any insight is appreciated.
