Thank you very much for the hint!Hi,
it possible now with virtio nic, and a patch have been added to proxmox recenctly, avaible in vm config but not in gui for now
https://git.proxmox.com/?p=qemu-server.git;a=commit;h=61a14cde8d568e552d3deaab2da76b479b8aca7b
edit your vm config file in /etc/pve/qemuserver/<vmid>.conf
net0: ......,host_mtu=1400
for example.
special value: host_mtu=1, will force the mtu to vmbrX mtu.
/etc/pve/qemu-server/100.conf
and that the line should look like this: net0: virtio=D2:69:F9:B7:FA:6E,bridge=vmbr4000,host_mtu=1400

part, the network device basically "disappears" from the Cloud-init Proxmox UI. Is this normal?When adding thehost_mtu=1400

Seems to be working, thank you! Any idea if this will be implemented in the UI at some point?the correct syntax is simply "...,mtu=1400"
yes, I'll try to send a patch next week.Seems to be working, thank you! Any idea if this will be implemented in the UI at some point?
Sounds great, thank you!yes, I'll try to send a patch next week.
Any news? Was the patch sent/applied, because I still can't see anything in the UI.yes, I'll try to send a patch next week.
Everybody is asking for this but it seems that we're basically ignored.Hello there!
Any news about this patch? Any help we the users can offer?
It would be really great to have this option.
Thanks
