hi,

is it a fresh proxmox6 install ?  or upgraded from proxmox5?

any /etc/udev/rules.d/70-persistent-net.rules file somewhere ?  (should be removed)

no special grub option ? (net.ifnames, ...)

Objet: [PVE-User] Network interfaces renaming strangeness...

I've setup a little 'home' PVE server: proxmox6 (debian buster, kernel 
5.3.18-1-pve). 

Bultin network card get detected and renamed: 

root at ino:~# grep tg3 /var/log/kern.log

Feb 11 09:16:44 ino kernel: [ 101.292208] tg3 0000:1e:00.0 ens1: Flow control is on for TX and on for RX 

After that, i've addedd a second nic, pcie slot, that get detected but 
'strangely' renamed: 

root at ino:~# grep e1000e /var/log/kern.log

Feb 11 09:16:42 ino kernel: [ 3.557393] e1000e 0000:20:00.0 rename3: renamed from eth0 

Looking at: 

https://wiki.debian.org/NetworkInterfaceNames 

Strangeness remain, look at: 

root at ino:~# udevadm test-builtin net_id /sys/class/net/ens1 
Load module index 
Parsed configuration file /usr/lib/systemd/network/99-default.link 
Created link configuration context. 
Using default interface naming scheme 'v240'. 
ID_NET_NAMING_SCHEME=v240 
ID_NET_NAME_MAC=enx9c8e997b86d9 
ID_OUI_FROM_DATABASE=Hewlett Packard 
ID_NET_NAME_PATH=enp30s0 
ID_NET_NAME_SLOT=ens1 
Unload module index 
Unloaded link configuration context. 

root at ino:~# udevadm test-builtin net_id /sys/class/net/rename3 
Load module index 
Parsed configuration file /usr/lib/systemd/network/99-default.link 
Created link configuration context. 
Using default interface naming scheme 'v240'. 
ID_NET_NAMING_SCHEME=v240 
ID_NET_NAME_MAC=enx2c27d7149b67 
ID_OUI_FROM_DATABASE=Hewlett Packard 
ID_NET_NAME_PATH=enp32s0 
ID_NET_NAME_SLOT=ens1 
Unload module index 
Unloaded link configuration context. 

AFAI've understood network names would have to be 'enp30s0' and 
'enp32s0' respectively, not 'ens1' and 'rename3'... 


Why?! Thanks.
