Hi,

You might be able to get VNC console through virsh, if you have configured
sasl auth with libvirt.

Then you could try to start the engine VM paused:

hosted-engine --vm-start-paused

then add a VNC password:

hosted-engine --add-console-password

Then try to connect with vnc and you may resume the VM:

virsh -c qemu://hostname.local/system resume HostedEngine

where hostname.local is the hostname part of the connection URI.

You might also get some insight from host logs (vdsm.log).

In my case, 99% of the cases was a storage issue that was causing engine to
not be able to boot.
