Hi,

Please see:

Sandro/Michal - perhaps we want to add something about this to the
front/download pages on the website.

Good luck and best regards,

I am a bit confused on this as the VM will get a DHCP address only after running the 'hosted-engine' script. What ip address should I have for the engine VM (say if I have my engine host name as ovirt-engine.my.cluster)? If I have no entry for the engine in the DNS I get the following error:
