[ovirt-users] Hosted Engine won't start, how to debug?

[Martin Sivak]

You need to be in global maintenance, but I think you already know that.
Then try updating the vm.conf like you already did and add this line:

devices={device:vnc,type:graphics,deviceId:f1d0394e-b077-4ea6-99e5-b9b6b8fe073c,address:None}

Then restart the VM using hosted-engine commands and try the VNC approach again.

Best regards
