[SOLVED] Startup for container failed - Failed to create network device

[Favo]

Hi together,

im near desperation. I´m trying to copy youtube tutorials 1:1 to setup my Proxmox and Pihole. Base is a Dell Latitute E6330. I am setting up proxmox and can go to the webinterface. Then I do the setup for deleting enterprise and adding the "not recommended repo". After this I am trying to create a debian 10 CT but when I try to start it im getting following Error:

netdev_configure_server_veth: 659 Operation not supported - Failed to create veth pair "veth101i0" and "vethy9clSL" lxc_create_network_priv: 3418 Operation not supported - Failed to create network device lxc_spawn: 1844 Failed to create the network __lxc_start: 2073 Failed to spawn container "101" TASK ERROR: startup for container '101' failed

Does someone knows what to do?

I´m using a fritzbox and my vmbr0 got the Adress: 192.168.178.77/24 and gateway 192.168.178.1 with bridge port eno1.

hi,

did you do upgrades recently? don't forget to reboot your PVE

if the container still fails after the host reboot, please post the outputs from:
* pct config CTID
* pct start CTID --debug

Hi Oguz,

if I press "reboot" is this the right way?

When I open up the shell and try to put in your commands it says:
400 Parameter verification failed.
vmid: type check ('integer') failed - got 'CTID'
pct start <vmid> [OPTIONS]

you can just run reboot on your PVE host shell (not inside the container)

When I open up the shell and try to put in your commands it says:
400 Parameter verification failed.
vmid: type check ('integer') failed - got 'CTID'
pct start <vmid> [OPTIONS]

and also replace CTID with the actual ID of your container

Sure my bad I am very new to this topics.

I did the reboot and the CT came online.
How simple but also despairing.

Thank you very much Oguz you are my hero!

i had same problem,when i start lxc , i got below error:

run_buffer: 571 Script exited with status 25

lxc_spawn: 1847 Failed to create the network
