PBS 2.4 as LXC container in PVE 7.4 no networking after reboot

[hagen]

After upgrading PBS 2.3.3-1 to PBS 2.4.1-1 the service doesn't start up. The PBS is running as an LXC container in PVE 7.4-3.

Apr 12 10:15:29 hf-pbs01 systemd[1]: Starting Network Service...
Apr 12 10:15:29 hf-pbs01 systemd[79]: systemd-networkd.service: Failed to set up mount namespacing: Permission denied
Apr 12 10:15:29 hf-pbs01 systemd[79]: systemd-networkd.service: Failed at step NAMESPACE spawning /lib/systemd/systemd-networkd: Permission denied
Apr 12 10:15:29 hf-pbs01 systemd[1]: systemd-networkd.service: Main process exited, code=exited, status=226/NAMESPACE

Apr 12 10:15:29 hf-pbs01 systemd[1]: Failed to start Network Service.

As a workaround I found out how to solve this problem:

1. Comment out all lines starting with `Protect` in the file `/etc/systemd/system/multi-user.target.wants/systemd-networkd.service`
2. `systemctl daemon-reload`
3. reboot the LXC container

Is there a better way to solve this?

Hi,

Could you check whether "nesting" is enabled for your container? See e.g. here [1] for a similar report.

If this doesn't help, could you post your container config (the output of pct config VMID)?

The container is priviliged without explicite nesting.

arch: amd64
hostname: hf-pbs01
memory: 4096
mp0: /daten/backup,mp=/backup,acl=0,backup=0,quota=0,replicate=0,ro=0,shared=0
nameserver: 192.168.xx.yy
net0: name=eth0,bridge=vmbr0,gw=192.168.xx.yyy,hwaddr=AA:BB:CC:DD:EE:FF,ip=192.168.xx.yy/24,type=veth
onboot: 1
ostype: ubuntu
rootfs: SDCARD:110/vm-110-disk-1.raw,size=5G
searchdomain: domain.lan
swap: 0

I'll try a new config:

arch: amd64
hostname: hf-pbs01
memory: 4096
mp0: /daten/backup,mp=/backup,acl=0,backup=0,quota=0,replicate=0,ro=0,shared=0

net0: name=eth0,bridge=vmbr0,gw=192.168.xx.yyy,hwaddr=AA:BB:CC:DD:EE:FF,ip=192.168.xx.yy/24,type=veth
nesting: 1
onboot: 1
ostype: ubuntu
rootfs: SDCARD:110/vm-110-disk-1.raw,size=5G
