Hi, Anthony

Which libvirt version do you use? If I'm right, it should be
caused by a recent patch.

    /* wait for qemu process to to show up */
    if (ret == 0) {
        if (virFileReadPid(driver->stateDir, vm->def->name, &vm->pid)) {
            qemuReportError(VIR_ERR_INTERNAL_ERROR,
                            _("Domain %s didn't show up\n"), 
vm->def->name);
            ret = -1;
        }
#if 0
    } else if (ret == -2) {
        /*
         * XXX this is bogus. It isn't safe to set vm->pid = child
         * because the child no longer exists.
         */

        /* The virExec process that launches the daemon failed. Pending on
         * when it failed (we can't determine for sure), there may be
         * extra info in the domain log (if the hook failed for example).
         *
         * Pretend like things succeeded, and let 'WaitForMonitor' report
         * the log contents for us.
         */
        vm->pid = child;
        ret = 0;
#endif
    }

could you check your guest log, and also libvirtd log?

/var/log/libvirt/qemu/$guest.log
/var/log/messages
