Host freeze if intel VT is enabled (Gigabyte)
Reported by: | woec | Owned by: | |

Component: | VMM/HWACCM | Version: | VirtualBox 3.2.6 |
Keywords: | VT-x, host freeze after S3 | Cc: | |
Guest type: | Windows | Host type: | Linux |
Description ¶
When resuming after having suspended (S3) and starting a VM with vt-x enabled, the host freezes. The VM runs without problems when starting it from host which was not ever suspended before since last boot. Seems to be same isssue as reported in #5048 and #7216.
Following new aspect: reading out the corresponding Machine register, which controls the VT-x function - IA32_Feature_Control (MSR 0x0000003a, Bits [2:0]) using the msr-tools (rdmsr), I got a value of 5 - which means VT-x is enabled. Result is 5, independently on machine history (S3 before or new booted machine). I found also that this register is write protected, I was not able to change its value by means of wrmsr. So I conclude, VT-x is enabled from the BIOS and it does not change its state while suspend and resume.
I am also quite sure, that the problem described here was not there on older versions of virtualbox under same machine configuration (maybe before 3.0.10).
My machine configuration: CPU: Intel E8400, Mobo: Gigabyte GA-EP35-DS3, 4 GB RAM, Debian Linux squeeze, kernel 2.6.32-5-686-bigmem
