[Xen-devel] Latest snap shot on FC4 problems

[Ted Kaczmarek <tedkaz@xxxxxxxxxxxxx>]

Using  2.6.12-1.1447_FC4xen0 from FC4 testing updates.
Xend will start most of the time, vm will rarely start, and even less
liklely to complete booting, most common error is
 "12, 'Cannot allocate memory'" at cli when starting vm.

Test machine is an SMP Atlon with 1 gig on ram.
