They have 256 entries on kvmtool, support that. Need more memory for virtqueues now. But with the move to 32bit drivers this should not be a big issue.
FIXME: Must bump to 260 to make things actually work. There seems to be some corruption otherwise and kvmtool complains about invalid requests. Not yet debugged who is at fault here.
