Set MTU on Guest

[spirit]

I don't understand why this was not integrated yet. There are clearly multiple use cases for this. It can be a hidden option (advanced checkbox) just like with the NICs for the host.

Thanks

it's not available in gui, but you can already add ",mtu=xxxx" with command line or in vm config file.

So this might come to the GUI?

Looking at the age of this post i would count on it short term. It is annoying though every change on the container you have to readd the mtu as it overwrites the config with its own settings.

Hi All, I needed this feature (mtu), so i had to correct patches from Tacid (good work, thank U).

patch -d /usr/share/pve-manager/js/  < pvemanagerlib_mtu.patch
patch -d /usr/share/perl5/PVE/ < qemu_server_mtu.patch

systemctl restart pvedaemon
systemctl restart pveproxy

Tested on:
pve-manager/7.2-3/c743d6c1 (running kernel: 5.13.19-6-pve)

Why wasn't this merged yet? A patch was send back in 2018, followed by other patches.

Thanks

MTU Settings are available for the PVE server network settings but not for the vm nic settings.
