[mythtv-users] Maintain Mythtv Uptime using Virtual Machine; Possible?

[lists_mythtv_users]

I need to install a new distro on my backend server.  I only have one 
backend containing all my tuners.  The mysql server is already on a VM 
that I can move to a different host on my LAN.  Is it possible to create 
a VM and create a tunerless master backend on it so that mythtv can 
still be used on my LAN to watch existing recordings while the real 
mythtv server is down for a rebuild?

Regards,

Steve.
