Is there a way internal to a KVM VM to know which host it's running on?
No. The ideal hypervisor is one where the guest doesn't even know it is running as a virtual machine. And consider live migration - a guest might not be running on the same host over its lifetime. Therefore, there should be nothing that requires a guest to know which host it is 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?
Why do you think you need it? Perhaps if you ask a better question about what you are really trying to solve, we can give a better answer. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
