Hi there.
I'm running a 5 nodes PVE6 cluster, and I'm using ifupdown2 templating features to create vxlan overlays between my nodes (setup this before the SDN feature went live). Here's a snippet of my /etc/network/interfaces :
%for i in range(1, 6):
%for v in range(0, 21):
auto vxlan${i*100+v}
iface vxlan${i*100+v}
vxlan-id ${i*100+v}
vxlan-mcastgrp 225.20.118.1
vxlan-physdev enp132s0f0.2018
bridge-access ${i*100+v}
%endfor
%endfor
auto vmbr0
iface vmbr0 inet manual
%for i in range(1, 6):
bridge-ports glob vxlan${i*100}-${i*100+20}
%endfor
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
Everything is working fine with ifupdown2-2.0.1-1+pve10 but if I update ifupdown to v 3.0.0-1+pve2, my vxlan aren't created anymore. An ifreload -a outputs these errors :
root@pve4:~# ifreload -a

error: vmbr0: bridge port vxlan${i*100}-${i*100+20} does not exist
(yes, python-mako is installed)
I had to downgrade ifupdown2 on all my nodes to get my network stack back online.
Is there a regression with templating support in ifupdown2 v3 or has something changed and must be adapted ?
Cheers,
Daniel

Hi,
ifupdown3 have migrated to python3,
maybe try to install python3-mako package ?

Didn't know it was switching to py3 :-)
Indeed, installing python3-mako makes the previous error message go away. But the result is even worst now, as ifupdown2 completly fails and don't even configure interfaces which are not using templates in /etc/network/interfaces

So it looks like ifupdown2 v3 is not fully compatible with config working in v2. Haven't digged yet into it (those are prod servers, so not easy to play with their network stack)

seem to be a bug here, maybe in template parsing.
Maybe this commit is fixing it:

That's it !
Installing python3-mako and applying this patch made everything working again. I guess it'll picked up on the next ifupdown2 release (or should this be backported in pve package ?)
Anyway, many thanks Alexandre !

I'll try to see if we can backport this patch, or bump to last master version, until a new release is done.
