[vmchecker-dev] vbox backend in libvirt

[Lucian Adrian Grijincu]

Hi,

After reading about in the sources of virtualbox and libvirt I came to
the conclusion that the vbox backend in libvirt does not support
snapshots properly.
it can only save (or, more correctly pause) a machine and stop it from
working and you can unpause it later, but you cannot run it and
restore it to a know state in the past.

libvirt can only restore snapshots for xen and kvm, so no openvz, vbox or qemu.
This sucks, we have can ditch libvirt for now.

We can still use vbox however, there's a commandline utility
"vboxmanage" that can do startup/shudown and snapshot/restore of vms.
The in openvz, we'd have to manually clean the dirty state the machine
is in after being run. This is trickier and more so if we choose to
allow kernel level access to guests.
