It is possible to use vdsClient / virsh to start VMs in the event that engine is down?
Hello all, I do not see a way to start vm's in the event that an engine is down. I see vdsClient -s 0 destroy works to shut them down. Also, is it still possible to use non-read-only virsh commands? i tried using saslpasswd2 to create an account, but that did not seem to work. Thanks!

Yes, engine is SPOF. They invented hosted engine solution which pretends to bringe HA for engine but... I have no idea why it does not use JBoss based features like clustering.

You are doing something wrong then. Auth for virsh works ok, you just have to know how libvirt works with that sasl :) # grep ^sasldb /etc/sasl2/libvirt.conf sasldb_path: /etc/libvirt/passwd.db # saslpasswd2 -c -a libvirt testovic ... # strings /etc/libvirt/passwd.db | grep ^testovic testovic j.
Thank you Jiri! I had tried this, but your post made me think of googling /etc/libvirt/passwd.db a bit more and discovered the sasldblistusers2 -f /etc/libvirt/passwd.db command which showed me 2 users including root@localbox...when I entered that user it worked. Still cannot start turned-off vms this way, but its furtehr than I got. Thanks again. On Fri, Oct 30, 2015 at 1:29 PM, Jiri Belka <jbelka@redhat.com> wrote:
