Given that it gives an error outside the VM, it's likely hardware. > Is there some way to recover the guest disk image without a > complete reinstall? Depending on where the error is, you might get away with dd'ing with conv=noerror,sync, changing vm.conf to point to the new copy, and run fsck in the vm. And buy a new hard disk or SDD. Probably cheaper than your time to further diagnose it?
