HI,
I was exploring more about ovirt-gueste-engin.
It look to me very easy to configure add add hook as script.
But my doubt is, how to invoke those script from ovirt-engine ?
Please some one help me to understand this part.
I am looking into python SDK code to figure out same but still not got luck
Thanks,
~Rohit

Guest agent hooks aren’t triggered through the SDK, hooks are triggered when certain
events happen on the hypervisor side.
e.g. A VM gets migrated from HOST A to HOST B or the VM gets suspended. In these cases
VDSM _can_ send a message to the guest
agent asking it to process all hooks.
That those hooks are enabled are depending on the migration policy configured. Currently
all but the ‘Legacy’ migration policies do cause the hooks to be executed, given a new
enough guest agent, VDSM and cluster version.

Hi,
It look interesting.
Would you please point me some document that cover in detail ?
I was looking for mechanism where I can monitor guest application.
If application get failed or crash then I need to restart or start other VM.
Is it possible in ovirt ?
I though I will use hook but as you explain it clear me that my understand
was wrong.
Thanks for your help.
Thanks,
~Rohit

No, there is nothing like this in oVirt, you would have to use something =
like zabbix and then connect it with the oVirt SDK
