Thanks Brian,

The kvm host with the problem is running:

* Fedora release 10 (Cambridge)
* kernel: 2.6.27   (the actual fedora package is 2.6.27.21-170.2.56.fc10.x86_64)

* 4x Quad-Core AMD Opteron(tm) Processor 8347 HE
* KVM version:  74 (the actual fedora package is (kvm-74-10.fc10.x86_64)

Reading some other post in forums, it seems kvm should be able to
handle > 4gb ram. Is this correct?

Best,

Mauro
