Public bug reported:

In the libguestfs driver for Nova VFS, certain errors in the setup
method can cause a libguestfs process to remain running, even after the
VM is terminated and/or the method that spawned the libguestfs VM has
finished.  These processes become zombies when killed, and can only be
destroyed by restarting nova-compute.

In the particular issue encountered, when using gluster as a cinder
backend and attempting to launch a VM before adding a keypair, the error
would occur.  However, it is feasible that the error could occur
elsewhere.
