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

["Jean-Michel Caricand" <jean-michel.caricand@xxxxxxxxxxx>]

Try with

system : Linux
host : persephone
release : 2.6.11.10-xen0
version : #1 Sun May 22 11:38:50 BST 2005
machine : i686
cores : 1
hyperthreads_per_core : 1
cpu_mhz : 400
memory : 256
free_memory : 435

for your host. 128Mo + 256Mo is < 512
