Re: [Xen-users] 10th Domain Error

[Mark Williamson <mark.williamson@xxxxxxxxxxxx>]

You've run out of loop devices: there's some kernel parameter for fixing this 
(you'll probably be able to find it in the mailing archives).  I think it's 
maxloop=n

You also need to create new loop[n] device nodes in /dev.

Cheers,
Mark
