Hi folks, I've noticed an issue during our sanity testing for upstream. On a RHEL 6 VM, After we issue the shutdown command, the qemu-kvm process is still alive for some reason, making autotest fail the test.

So even though the machine is shut, the vm process is still alive and then kvm-autotest considers the test as failed. The message 'Could not find (qemu) prompt after command' is from autotest, means that the monitor didn't return a prompt, as usual, which probably means the process is alive but not functional. kvm.git version: 11/24 14:27:19 INFO | kvm_utils:0407| Commit hash for git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git is 2a663fe561c625c1cd9707804df632e3cf1f982a (tag v2.6.32-56687-g2a663fe) qemu-kvm.git version: 11/24 14:48:37 INFO | kvm_utils:0407| Commit hash for git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git is b377474e589e5a1fe2abc7b13fafa8bad802637a (tag kvm-88-6260-gb377474) guest: RHEL 6.0 64 bit, installed from the release CD.
