Comment 1 Mike A. Harris 2001-10-30 02:33:02 UTC
Red Hat Linux does not officially support using KVM switch boxes.  Many
of these devices work fine, while others do not.  Some of the problems
are software related, and some are the actual devices themselves.  Since
we do not have all of this hardware, we cannot actively support it.

Comment 2 Mike A. Harris 2002-11-09 00:45:05 UTC
I'd also like to add, that 99.99999% of all KVM related bugs, are the
KVM itself causing the problem.  It is rarely if ever a software problem.
