Error when saving changes to virtual system

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 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



Howdy -- which Cloudmin version is it that you're using there, is that Cloudmin Pro or GPL?

I use Cloudmin GPL. The error crops up on any changes attemps, in the Edit System screen, such as: - Switching start up option at boot time - Changing Operating System list menu - Enabling High Resolution Graphics - Adding a note

Check that the hostname can actually be resolved by your Cloudmin master system.

The problem may be that your DNS server is down, that the record was removed, or that your system isn't querying it's own DNS server.

Jamie's ideas above will hopefully get you started... it doesn't sound like you're seeing a bug there though.

Since you're using Cloudmin GPL, if you had any followup questions, you'd want to ask those in the Forums.

We monitor the Forums, along with lots of wonderful folks in the community. Thanks!

Thank you for your answer. Server name was actually not resolved. I added server name to /etc/hosts and issue was resolved. I will investigate Bind issue further. Best regards,
