[ovirt-users] split brain scenario?

Hi, according to HA VM documentation, a paused VM may be started on another host and later resumed on the original host. - https://www.ovirt.org/develop/ha-vms.html here, I'm assuming the HA VM was paused due to I/O error. but I'm wondering how it can happen because I guess the HA VM will be restarted on another host only after it's completely killed from the original host. can you give the split brain scenario?
