[Xen-devel] page allocation failure

[sai srinivas dharanikota <saisrinu31@xxxxxxxxxxx>]

Hello,

I have setup 2 virtual partitions. When I try to start
unicore client on one of the virtual machines the
following message is displayed and the unicore client
is hanged. I dont understand why there is a page
allocation failure. I would appreciate if any body has
pointers to my questions.

Thanks in advance,
Sai
