how to determine is system is KVN, Openvz or hardware?

how to determine is system is KVM, Openvz or hardware?

for some scripts, we need to know the type of system.. we are concerned with linux systems only.

so what do I test for:

openvz : true if /proc/vz exits

kvm : true if ?

otherwise : hardware .

I have not been able to figure out how to tell if a system is kvm or hardware.

In case anyone knows, please reply.

thank you

Hi,
whats about

cat /proc/cpuinfo | grep "model name"

if the cpu is QEMU you have an kvm-machine.
But i don't know the output if you use "cpu=host"...

Are you sure there's no way fake out the CPU name and replace Qemu with something else?

where / why would 'cpu=host' be used?

so far this works:

cat /proc/cpuinfo | grep "model name" | grep QEMU && KVM=Y ; echo $KVM

Look here for explanation :

http://www.linux-kvm.org/page/Tuning_KVM

This is set in your /etc/qemu-server/VMID.conf with this :

args: -cpu host
