I think I've seen this one, and if so then it has been fixed but the
problem may not have made it out to Fedora yet (it was a bug in Xen
itself).
It was caused by Domain-0 not being able to balloon down its memory
usage by enough to accomodate the new domain. The workaround is to
reduce the amount of memory allocated to Domain-0 manually first, eg:
virsh setmaxmem 0 128000
but you'll have to modify '128000' to be some amount of memory in
kilobytes which is the current Domain-0 allocation, less what is needed
for your new domain, less a bit more for good luck...

Hi Richard,
I tried "virsh setmaxmem 0 512000" and then the system hung and i had to
reset it. After the system is started again i can start the windows
guest domains now, but the state is blocked.
Why is the state blocked and not running? Which tools can show me why
the state is blocked?
I'm running F7 on a Dell PE2950 with 8GB RAM.
It would be nice if you could explain how much RAM i should allocate to
Dom0 and what are the minimum requirements for Dom0.
Thank you in advance,
Thomas
