3525MB RAM Limit

Hi,

I'm running a KVM host using Fedora 10 (x86_64) on 4x Quad-Core AMD
Opteron(tm) Processor 8347 HE system with 16GB ram. I've created a
Fedora 10 (x86_64) guest and allocated 8 CPUs and 8GB ram which I can
see using 'virt-manager'. When I login to the guest, I can see the 8
CPUs, but apparently, I only have 3525MB RAM (output from 'free'). At
first I thought it was a 32bit problem, but I've double checked and
the host and guest are both running 64bit architectures. virt-manager
shows 50% ram usage which appears to be correct (4GB, out of 8). It
also correctly recognises the 16GB available in the host machine.

Is this expected? Will the extra ram become available once it is
required? If not, does anyone have any Ideas for how I can fix the
problem?

Thanks,

Dan
