I use KVM virtualization Cloudmin 9.2 on Ubuntu 16.04.1 server
All guest systems work fine, but when I try to save changes, I get this error message and found no way to circumvent. Failed to save system details : "The new hostname myhost.cloudmin.net cannot be resolved to an IP address."
The issue is present only on some systems, possibly those created most recently.
Tried to restart Bind but no improvement. Thank you for any help you can provide. Regards
