I am having an issue where domU will not report more than 1GB of memory even while xm list is showing 1.5GB.

when starting domU with more than 1GB of RAM it only reports 1GB <using cat /proc/meminfo while in domU>. xm list in dom0 clearly shows the 1.5GB allocated in the config file and by trial and error (manipulating the mem in dom0 I am sure it is at least trying to allocate the 1.5GB).

I am on a machine with 2GB of physical RAM and allocating 256MB to dom0. Am I hitting some type of limitation here (xen 2.0.1 on FC3) I am attaching the output from xm list and <cat /proc/meminfo>

Dom0: xm list

Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 245 0 r---- 1202.9
xm6 10 1535 1 -b--- 3.8 9610


DomU : cat /proc/meminfo
