Stop LXC container changing the container hostname

[Taomyn]

How can I stop LXC changing the changing the container's hostname to that of the container?

My preference is for the label you see in the console to be just the name e.g. 101 (FRED), but the container or VM the hostname to be fred.mydomain.com but when I do this LXC changes it back.

This works for VMs but I can't see how to stop the hostname in the container being changed.

Have you tried "touch /etc/.pve-ignore.hostname" inside the container? Or you could try setting the container to unmanaged:

Yes, I tried the ignore and it didn't work



I didn't know about the "unmanaged" option so I will try that - just hope I can set up what doesn't then get set up e.g. network settings

I tried setting it to unmanaged, and it still changes it

I think you will need to reset the hostname manually inside the container after making the changes. Other than that I'm out of ideas.

Tried that twice and rebooted after I changed it to unmanaged in case it was something like that, but still the same.

Do you think I should report it as a bug, especially if it's still changing things when set to unmanaged?
