Hello, I have an odd problem on a dual processor, dual core Opteron system. Obviosously it is x86_64 so should have no problem large amounts of RAM. The system has 4 GB installed (2GB on each processor). If I boot the system with a fresh install of Debian Etch it sees all the memory fine. dmesg reports: Memory: 4107008k/5242880k available (1929k kernel code, 86836k reserved, 864k data, 176k

I just discovered that my xen hypervisor only believes that it has 3199 MB of memory, when there are 4GB inside the computer. I don''t know how long this has been this way, but I do not know how to try and force the hypervisor to realize how much memory it has. Any ideas how I can accomplish this? I am running CentOS 5 (RHEL 5), kernel 2.6.18-53.1.4.el5xen, x86_64, xen 3.0.3.

Hi all, On dual core processor machine, I installed ubuntu-8.04 in which I installed xen-3.2. In ubuntu: # cat /proc/cpuinfo --> Shows two processors information. But in Xen on the same machine: # cat /proc/cpuinfo --> Shows only one processor information. Can anyone please explain what could be the reason behind this? Thanks Saravana
