Hello, I am not sure if this is the correct Mailing list for the issue I have. I have a new system with 18GB of Physical memory on the system. I loaded CentOS 6.4. But when I boot into Dom0, I only see (xm info) 2GB of total memory? I set 1GB for Dom0, but I am not sure why the hypervisor does not see all the memory.
