I'm sure the VM systems are great, but as I said above,
*I would not hold my breadth* that VM:s are deployed in
great numbers and replacing all the existing hosts/servers
any time soon... it will take time and by that time you
could use Mondo, free software with no additional costs,
works with existing HW, current Linux configuration etc.

I'm willing to believe that VM is nice solution as
far as the HW is properly implemented and you have
separate service processor (built in chassis that
stays powered as long as power cord(s) are plugged
and you can access all the HW configuration via
that thus being able to power down CPU(s) etc).
I wouldn't really trust and even though I have seen
quite a many nicely built PC servers, none of them have
matched the reliablity and remote manageability of
HP, IBM and Sun HW. AFAIK the truth is that however good
and reliable your VM sofware is if that's running
on general dog-shit PC HW, it's not worth much when
Mr Murphy is considered too.
IMHO, there is no much point also continuing this conversation
any more, all worth saying has been said continuing from here
would make us just repeat ourselves. Thanks anyways for the
comments and critics too :)
For short, I suggest that Red Hat tries Mondo and seriously
considers including it ASAP to next distro and that's about
it for now.
HTH,
