So in trying to use keys instead of root/password, per the ovirt GUI I
enter the address of the host, specify port 2222 (sshd listening here
will allow ssh into root via keys), check the "SSH Public Key" button,
copy the contents of the key provided in the UI to the
/root/.ssh/authorized_keys
file on the node being added, and get:
Error while executing action: Cannot install Host with empty password.
The logs show:
WARN [org.ovirt.engine.core.bll.AddVdsCommand] (ajp--127.0.0.1-8702-6)
[750e08ac] CanDoAction of action AddVds failed.
Reasons:VAR__ACTION__ADD,VAR__TYPE__HOST,$server
*our_server's_hostname*,VDS_CANNOT_INSTALL_EMPTY_PASSWORD

CC'ing Yaniv Bronheim who was the feature owner for ssh fingerprint usage
during host addition.
I guess Yaniv can confirm exactly which version it was added.
