[Xen-users] migrate existing non-xen system to a VM?

[Miles Fidelman <mfidelman@xxxxxxxxxxxxxxxx>]

I know that I've seen this discussed before, but can anyone point to a 
concise description of how to take an existing, non-xen machine (in this 
case a system running Debian Lenny), and,
1. shut it down
2. package up the state
3. move it into a VM (assume there's a 2nd computer, with Dom0 up and 
running, on the same LAN)
4. start the VM and end up with a virtualized version of the original 
environment chugging away
A little context:  I'm trying to add hot-spare failover to a production 
system (email, list services, web server, database) - by moving from a 
standard Debian Lenny install to Debian Lenny running as a VM, backed by 
DRBD, set for failover.  The first step is to get the production 
environment into a VM, and then I can set up all the failover stuff.
So... the above is just a little more complicated, in that there are 4 
partitions that have to be moved:
/boot - raided volume --> xen setup on new machine
/swap --> drbd device on new machine, mounted in VM
/ --> drbd device on new machine, mounted in VM
/backup (another volume) -> drbd device mounted in VM

I'm currently proceeding down the path of replicating the environment in 
a running VM, preparing to manually migrate config. and user data.  But 
if there's a simpler way, any suggestions would be very much appreciated.
Thanks,

Miles Fidelman
