[SOLVED] LXC dns from dhcp

[belrpr]

Hi,

is there an option to get the dns settings from the dhcp server rather than manually putting it in or using the host defaults?

I've got a lot of vm's which are booted in a dmzand now.

Thx for the help!

I guess you are talking about containers, because PVE does not do the actual network setup inside VMs?

you can tell PVE to not touch the /etc/resolv.conf file (or equivalent, depending on guest distribution), then the network setup tools of the container should be able to use the information obtained via DHCP. but I guess that is highly dependent on the actual distro and tools used

This line worked just fine:

touch /etc/.pve-ignore.resolve.conf

There is a small typo in the file path from the previous command:

-.pve-ignore.resolve.conf
+.pve-ignore.resolv.conf

So the command to run is:

touch /etc/.pve-ignore.resolv.conf

And, because I did not find the information anywhere, this file must be created inside the container and not on the host system.
