Re: [Xen-users] Error creating domain: (12, 'Cannot allocate memory')

How do I set that up?  I have tried setting the dom0_mem argument in 
grub, I have tried setting the mem argument in grub, I have tried to 
use balloon, etc, all to no avail.
When I run xm info, I see that there is 435 MB free.   Why is this not 
being used?
Thanks in advance.
