I have tried this, but it doesn't work. I get a:
felis:/etc/xen# xm create dhcp1.cfg -c
Using config file "dhcp1.cfg".
Error: Device 2049 (vbd) could not be connected.
Device /dev/vm_volumes/root.dhcp1 is mounted in a guest domain,
and so cannot be mounted now.
I've checked and I don't have any volume mounted. I have also try to
completely stop lvm system with the same result.

OK, I have tried with a domU kernel that supports and that doesn't
support it with the same results.

logical volumes are working right, as I can mount them in the dom0.

If I try with this config:
kernel = "/boot/xen-linux-2.6.12.6-atica-xenu"
memory = 256
name = "dhcp1"
vif = [ '' ]
disk = ['phy:vm_volumes/root.dhcp1,xvda1,w',
'phy:vm_volumes/var.dhcp1,xvda2,w',
'phy:vm_volumes/swap.dhcp1,xvda3,w']
root = "/dev/xvda1 ro"
I get the same result:
felis:/etc/xen# xm create dhcp1.cfg -c
Using config file "dhcp1.cfg".
Error: Device 51713 (vbd) could not be connected.
Device /dev/vm_volumes/root.dhcp1 is mounted in a guest domain,
and so cannot be mounted now.
