Thanks, Eric. Having made that MAC address mistake before, I did make sure the MAC's were different before starting the domU, and I've since rebooted.

I just looked in xen-hotplug.log, and found:
/dev/loop10: No such device or address
xenstore-read: couldn't read path backend/vbd/3/2049/node

And when I try to mount more than 8 images, I get a no loop device available error. So it's definitely a problem with the number of loopback devices. Since the loopback device appears not be in my kernel, passing the max_loop paramter in will not work. I think I can increase the number of devices in the initrd somewhere. I am rather curious why the loop device number incremented from 0 to 1 to 10? Any ideas?

Thanks,

Eric

Sure did. All the domains have distinct statically assigned MAC addressses. Here are the three respective vif lines:
vif = [ 'mac=00:16:3e:aa:06:21, bridge=xenbr0' ]
vif = [ 'mac=00:16:3e:c4:20:11, bridge=xenbr0' ]
vif = [ 'mac=00:16:3e:00:03:11, bridge=xenbr0' ]


Is there a possibility you accidentally tried to start one of the domains with an already assigned MAC address?
(before realizing and correcting it, of course)

I ask because I ran into the same error as you're seeing once I started assigning MAC addresses. I accidentally assigned two domains the same mac address, fixed it, but still couldn't create new DomU until I rebooted.
