Corosync/pacemake uses completely different way how to perform fencing and
this is not applicable for oVirt.
But oVirt also uses shared storage information (we call it storage leases)
which can detect that host is still running and only connection between
enigne and host is broken. For details about VM leases please take a look:

You can specify custom firewalld rules, which are applied during host
installation/reinstallation:

https://ovirt.org/documentation/admin-guide/chap-Hosts.html#configuring-host-firewall-rules

So is there anything you are missing?

I think poison pill-based  fencing is easier  to implement but it requires 
either  Network-based  (iSCSI or NFS)  or FC-based  shared  storage.

It is used  in corosync/pacemaker clusters and is easier to implement.

This RFE has been filed in 2016 and didn't got much interest so far. Can
you elaborate a bit on the user story for this?
