Hi.
There are 2 nodes:
10.2.20.8 and 10.1.20.7
Migrate virtual machines from 10.2.20.8 to 10.1.20.7 is successful.
But when trying to migrate from 10.2.20.8 to 10.1.20.7 error:
Migration failed due to Error: Migration destination has an invalid hostname
(VM: 1, Source Host: 10.1.20.7).

How do I fix it?
I checked the host name on both nodes and found that they resolves correctly
(there is an entry in /etc/hostname).
In DNS hostname is not registered (!)
