I was playing with UI and found an issue when removing assigned devices. NPE in the log and weird behavior

Time: 2015-10-24 09:05:02,871
I had a VM with several devices assigned and only one host (not properly configured for passthrough) and tried to Run it

Time: 2015-10-24 09:06:05,921 and around:
Then I tried to remove the devices (not all at once, in 3 steps) and during the removal of the last one I received an empty result, device disappeared from the UI but apparently remained in backend - after switching tabs the device was still there

Comment 1 Michal Skrivanek 2015-10-29 15:11:36 UTC
seems it left the VM in some inconsistent state as it can't be run ever again even when all devices are removed and engine is restarted

Comment 2 Martin Betak 2015-11-24 11:41:55 UTC
The issue of failing to run the VM has already been fixed in 3.6. Marking as duplicate.

The '[]' in devices removed may appear in cases when you issue the remove commands too quickly and the device has already been removed as a result of previous bulk command. In that case the second operation is NO-OP thus resulting in "empty list of devices has been removed" message.
