Do you mean that you want to run a kernel in another VM? I think it is not possible. I have checked it. In a qemu with kvm enabled, # cat /proc/cpuinfo | grep ^flags flags : fpu de pse tsc msr pae mce cx8 apic sep pge cmov mmx fxsr sse sse2 up pni popcnt hypervisor It does not have "VMX" in flags. That means the vm does not have vt support.
