When a storage error occurs, VMs should pause, not migrate. However, if the VMs were io-idle, then pause (qemu EIO) might have not been triggered before hosts started dropping into non-op. ...which triggered a migration storm for HA-enabled VMs, racing with VMs pausing somehow (can't tell without diving into the logs for sure).
