For paravirtualized guests I don't think you need the hardware virtualization assist (VMX). You only need vmx when you want to create HVM guests.

No i just need to enable virtualization flag on my intel xeon quad core processor, so that i can create paravirt VMs in my set-up. Which at this time virt-manager is not allowing me to do.

Any plans for 'nested' VMX support? KVM seems to have that..
