Bug Description

1, version
ubuntu@ms01a:~/ming$ uname -a
Linux ms01a 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:10:54 UTC 2014 aarch64 aarch64 aarch64 GNU/Linux

2, kvm instance can't be launched, and see below failure log in /var/log/nova/nova-compute.log:

2014-11-05 21:58:58.480 781 INFO nova.compute.manager [-] [instance: 1e3bc825-b44f-47ee-b438-2fc06b133f5d] During sync_power_state the instance has a pending task. Skip.
2014-11-05 21:58:58.697 781 ERROR oslo.messaging.rpc.dispatcher [-] Exception during message handling: internal error: early end of file from monitor: possible problem:
qemu-system-aarch64: -serial pty: Failed to create chardev
qemu: could not connect serial device to character backend 'pty'

3, once I have done below change, the problem is fixed:

nova/virt/libvirt/driver.py:
            #consolepty = vconfig.LibvirtConfigGuestSerial()
            #consolepty.type = "pty"
            #guest.add_device(consolepty)

Is this still an issue in OpenStack master? A lot of multi arch serial support has been added there.
