I have implemented a delay start of 60 seconds which used to be enough. Is this delay also respected when the HA resources/VMs are managed by HA?


You mean the delay when you configure the guests to boot when the host is starting? I haven't tested it explicitly but HA should not take that delay into account.

In the task log you should see the start jobs for each VM and if there is a problem starting it, those would be the first place to look. Otherwise the syslog.

Take down/disconnect the interface over which corosync communicates. The isolated node will fence itself after it lost connection to the quorum part of the cluster.
