[Fedora-xen] add 2 lvm to guest with virt-manager

[Mark Nielsen]

Are you trying to use 2 logical volumes to separate / and /boot inside 
the VM, or present 2 logical volumes (which would show up as 2 separate 
disks entirely, xvda and xvdb for instance) to the guest from domain-0?

If all you want to do is have 2 separate logvols for / and /boot, then 
just present 1 logvol to the guest (which would show up inside the guest 
as xvda). Then you just partition that like any other physical disk into 
logical volumes (as many as you want, /, /boot, /var, /home, et cetera)

If you are trying to present 2 logvols to the VM itself, those will show 
up as 2 separate disks inside the VM, as I mentioned (xvda, xvdb, or in 
HVM sda, sdb, .. you get the idea) and I would wonder why you would want 
to do that.
