Re: To KVM or not to KVM

["David A. Parker" <dparker@utica.edu>]

I think that the virtualization support in some CPUs is not compatible 
with KVM.  I have an HP server with two dual-core Xeon model 5160 CPUs 
in it.  According to Intel's website, this CPU has the VT-x extension 
for virtualization support, and I enabled virtualization support in the 
BIOS.  However, QEMU says that the CPU does not support virtualization, 
and /proc/cpuinfo does not show the vmx extension (which KVM requires).
