[ovirt-users] Leaving maintenace mode

[Martin Sivak]

Hi,

the appliance we publish actually does not enable the ISO domain on
the VM anymore for exactly this reason. I believe we mention this in
the documentation somewhere too.

Please do not put or disable all domains that are served from inside
the engine VM.

Best regards
