If you run "xm mem-set " you should be able to allocate that memory to domain 0 (if it needs it)
xm mem-set 0 512
Would allocate 512MB to domain 0.

Hi,
i had installed the last updates for FC6 in a machine with 1 Giga of RAM.
The machine's ip is 136.145.116.88.

then, shutdown the virtual machine, and i did not get back the lost 250
Mbytes of RAM.
anybody knows how to get back my physical memory after to shutdown the
virtual machine? is that behavior a bug?
if i run two virtual machines, my physical memory is reduced until 512 MB
of Physical RAM. At this time, the only way to get 1Gbyte of RAM is
rebooting the machine :-(.
Thanks a lot for your suggestions.
