[libvirt-users] Compatibility with Parallels Virtouzo

[Matthias Bolte]

Well, as Virtuozzo is a variant of OpenVZ it'll probably be possible
to teach the OpenVZ driver to detect and deal with this similar to the
QEMU driver dealing with different variants of QEMU.

Is this filed just named differently, or did Virtuozzo completely
remove this ID?

If it's just named different then this should be simple to fix, but it
needs someone to figure this out.
