Can a VM tell what host it's on?

[Whit Blauvelt <whit.virt@xxxxxxxxxxxxx>]

Is there a way internal to a KVM VM to know which host it's running on? 

It could send a command via ssh to virsh on a host, and learn from that
whether the host currently has it running. But is there something within the
VM itself which will reveal this? 

Thanks,
Whit
