Re: [Xen-users] Only able to start 2 domUs

[Eric E <whalesuit@xxxxxxxxx>]

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
