[ovirt-users] Regarding VDSM_Hooks

2019-07-05 Thread Vrgotic, Marko
Dear oVIrt,

Happy to report I have deployed my first python vdsm_hook which removes A, 
, TXT records of VM each time after_vm_destroy event is triggered, and it 
works fine.
This was required to be able to quickly redploy/rebuild VMs using same hostname.

Issue I am observing/just discovered now is:
Since live_migration of VM guest is considered a destruction from Host 
perspective, DNS records get deleted and VM lands on new host without being 
resolvable  .

I would like to introduce another python script for hook regarding migration 
events to get these entries back into DNS but for that I need there IPs.

Question:

  *   Where can I find/locate/read VMs IPs and Hostnames (is it dom_xml) to be 
able to incorporate them for DNS Update script?
Or even better:

  *   What would be even better, is there a way to not trigger the dns update 
if VM is being Migrated? Can I use dom_xml or other location to check wheter VM 
is migrated  or not,  which would allow me to control if dnsupdate should be 
triggered or not


If its relevant for the question: we are currently running oVIrt 4.3.3 version

Kindly awaiting your reply.
