Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: Validating the number of unmanaged USB controllers for a restarted/rerun VM was done after the VM was already started to run but before a host was scheduled for this VM. Consequence: In case the validation failed, an error was displayed in audit log with host_name="UNKNOWN" - since no host assigned. I.e.: Failed to restart VM <vm-name> on Host <UNKNOWN> Fix: Add this USB unmanaged controllers validation check to the Validate() phase before the host started to run. Result: In case of a validation failure, a popup window will be displayed and a log msg will be added - informing that this VM can't run (without any host information included in the message).

Comment 2 Sharon Gratch 2017-05-09 11:27:50 UTC 
To reproduce this bug:

1. Add at least 2 un-managed USB controllers to an OLD VM <= 3.6, with USB policy set to DISABLED 
2. Restart the VM by HA or rerun it  - on a new 4.1 engine.

Since the USB devices validation of unmanaged USB controllers number failed in runVmCommand->initVM() phase (where there is still no host scheduled to run this VM), then an error is displayed in audit log with host=NULL (=UNKNOWN).
Comment 3 Jiri Belka 2017-06-19 12:14:26 UTC 
ok, ovirt-engine-4.1.3.4-0.1.el7.noarch

(i tried to reproduce it based on #2)
