Can't create vmbr0 on clean installation

[Hanz]

Dear All,
Came across a nasty problem after installing Proxmox 5.1 on Debian 9.
Cant' create initial bridge vmbr0 and bridge it with eth interface. Get error:
Can't use an undefined value as an ARRAY reference at /usr/share/perl5/PVE/INotify.pm line 1181. (500)

Any ideas on what could get wrong?

Maybe interaface names not eth0

Change default network name (ens33) to old “eth0” on Debian 9

vim /etc/default/grub

change:

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

and

grub-mkconfig -o /boot/grub/grub.cfg

reboot

Hi Hollis

Yes, exactly, the network interface named eno1, i have make change in the /etc/default/grub and run the grub-mkconfig -o /boot/grub/grub.cfg, after reboot, the interface name change to eth0.

from the GUI interface, I tried to create an bridge interface, but same error :

Can't use an undefined value as an ARRAY reference at /usr/share/perl5/PVE/INotify.pm line 1187. (500)

I usually add this bridge interface to the file /etc/network/interfaces, but i don't find him.
On the other hand, i find the config networking in /etc/systemd/network/50-default.network !

Best regards

Make changes with hands and reboot?

~# cat /etc/network/interfaces
auto lo

iface eth0 inet manual

iface eth1 inet manual

auto vmbr0

When i run the command cat /etc/network/interfaces :

cat: /etc/network/interfaces: No such file or directory

I tried to create it manually with the parameters that you put them, and restart the networking service :

May 24 11:28:41 ns369117 systemd[1]: Starting Raise network interfaces...
May 24 11:28:41 ns369117 ifup[9123]: Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).

Failed to start the servcie.

Like whats i said, the configuration file is located in /ets/systemd/network/50-default.network

# cat /etc/systemd/network/50-default.network
# This file sets the IP configuration of the primary (public) network device.
# You can also see this as "OSI Layer 3" config.
# It was created by the OVH installer, please be careful with modifications.

All my instalation Debian 9 (and older) uses /etc/network/interfaces
Netinstall ISO without any Windows Manager

 

[Mehdi_BE]

actually, my old Proxmox servers that I have installed, I find the file /etc/network/interfaces, but with this fresh install in a new server,
I fall on this new config.

Any advice for this issue please ?

 

[Hollis]

Reinstall and use legacy network config without systemd - NetInstall ISO

 

[storchi]

Reinstall and use legacy network config without systemd - NetInstall ISO

or place your systemd network config like there:
hxxps://wxw.freedesktop.org/software/systemd/man/systemd.netdev.html
cs
