Restoring Windows VM with Running Linux VM inside causes host system reset
|Reported by:||klichota||Owned by:|
This bug is related to ticket #6058.
I am running Windows XP (SP3) virtual machine on Linux (Ubuntu 8.04-derived distro) host. Inside this VM I have installed VirtualBox 3.0.12 and created VM for Linux guest (again Ubuntu 8.04-derived distro).
I have run the guest (and it is really slow) for quite long time and saved the outer (Windows) VM state (without stopping inner VM).
When I have tried to restore Windows VM state, the host (Linux) system got hard-reset - no oops, no dump, just went directly to boot procedure (BIOS, etc.). No trace of reset in host kernel logs.
I reproduced it a few times, although sometimes it did not happen (I think the inner Linux VM must run for some time for it to happen).
My processor does not support VT-X, so hardware virtualization was not used.
The kernel on host is standard Ubuntu kernel 2.6.24-24-generic.
