Hi Jenny/Martin, Any idea what I can do here? The hosted engine VM has no log on any host in /var/log/libvirt/qemu, and I fear that if I need to put the host into maintenance, e.g., to upgrade it that I created it on (which I think is hosting it), or if it fails for any reason, it won't get migrated to another host, and I will not be able to manage the cluster. It seems to be a very dangerous position to be in.
