Re: [Xen-users] cloning guests between Dom0's ?

["Ferreira, N. L. (Nuno)" <n.l.ferreira@xxxxx>]

I wrote those steps mainly based on :

http://www.howtoforge.com/linux_lvm
http://www.howtoforge.com/linux_lvm_snapshots

From my experience (short), I was able to clone VM's (SL 47) this way 
(and backup of course). No problems in particular.
Instead of using tar, dd could also be used (but larger files).

Is there a better way to do this? I'm just a newbie on this strange 
world, trying to do my best ;-)
Cheers,
N.
