How reproducible:

Steps to Reproduce:
1. hotplug/hotunplug NIC to/from VM

Actual results:
hotplug/hotunplug NIC fail

Additional info:
When running with XML-RPC I don't have this issue

Comment 2 Piotr Kliczewski 2014-09-29 12:54:13 UTC
It looks like ret value of hotunplugNic us None.

Comment 3 Oved Ourfali 2014-09-30 05:42:18 UTC
Antoni - does that require an additional fix, or can we move that to POST?

Comment 4 Oved Ourfali 2014-09-30 05:56:12 UTC
*** Bug 1147505 has been marked as a duplicate of this bug. ***

Comment 5 Dan Kenigsberg 2014-09-30 08:15:12 UTC
Piotr's patch only converts the TypeError to a hand-crafted exception. It does not solve the underlying problem (how come does hotunplug return None for vmList), which is still being researched.

Comment 6 Martin Pavlik 2014-10-07 14:55:30 UTC
works in vt5 (vdsm-4.16.6-1.el6ev.x86_64)

hot plug/unplug with JSON enabled is fine
