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.
