On ovirt-ha-broker side the detection is based on a strict string match on
the error message that is expected to be exactly 'Virtual machine does not
exist' to set down status otherwise we set unknown status as in this case:
https://gerrit.ovirt.org/gitweb?p=ovirt-hosted-engine-
ha.git;a=blob;f=ovirt_hosted_engine_ha/broker/submonitors/
engine_health.py;h=d633cb860b811e84021221771bf706a9a4ac1d63;hb=refs/heads/
master#l54
Adding Francesco here to understand if something has recently changed
there on vdsm side.
That’s not a very robust code handling.
Yes, the text changed, the vm id was added.
And yes, it may change again any time I guess
I agree, we are going to move to code check:
