Hi Dan,
Thanks for getting back to me & for your help. The script is 755 permissions and oVirt sees it under the host hooks as well. The dump is below:
(I replaced our node IP with “mynodeIP” for privacy) I don’t see the IP’s from the custom property listed in the dump and I also don’t see any errors in the vdsm log. If I grep multiips in the vdsm log I can see entries, but none appear to be errors.
Grep vdsm log for before_vm_start shows:
Thread-79534::DEBUG::2016-12-18 12:24:45,006::commands::68::root::(execCmd) /usr/bin/taskset --cpu-list 0-23 /usr/libexec/vdsm/hooks/before_vm_start/multiips (cwd None)
Then if I grep the path:
cat /var/log/vdsm/vdsm.log | /usr/libexec/vdsm/hooks/before_vm_start/multiips
Traceback (most recent call last):
File "/usr/libexec/vdsm/hooks/before_vm_start/multiips", line 6, in <module>
import hooking
ImportError: No module named hooking

Hello,
Following up on the users list as opposed to Bugzilla.
Thanks for helping out with this, much appreciated. I was able to get the custom property added in the engine & I can select the property, then enter in the IP’s.
I’m not sure if I created the hook correctly, as it doesn’t appear to have made any changes so far, only one IP communicates.
I created a file called “multiips” in the /usr/libexec/vdsm/hooks/before_vm_start/ directory containing the info from the Bugzilla thread.
Is there another step I should take or perhaps I’m missing something?
It should have been enough, but apparently something's missing.
Is the multiip script readable and executable?
Do you see any errors in vdsm.log when you start the VM?
Do you see the requested ips in the output of
Virsh -r dumpxml yourvm
