[Bug] Container (Network card turned off)

[Drthrax74]

Hi,

I think is a bug with parameter link_down=0 with command pct create .

When i use link_down=0, the network card is turned off.

When I created a container without these settings, it's fine.

Variables:

clear;
DATASTORE_CT=Data
DATASTORE_TEMPLATE=local
VMID=103
POOL=100.LXC
TEMPLATE=debian-12-standard_12.7-1_amd64.tar.zst

Download Template

pveam remove $DATASTORE_TEMPLATE:vztmpl/$TEMPLATE;
pveam download $DATASTORE_TEMPLATE $TEMPLATE;

Stop & Destroy LXC:

pct stop $VMID;
pct destroy $VMID 2>/dev/null;

Create Container:

pct create $VMID $DATASTORE_TEMPLATE:vztmpl/$TEMPLATE \
--template 0 \
--unprivileged=0 \
--pool $POOL \
--ostype alpine \
--hostname Alpine \
--timezone Europe/Paris \
--storage $DATASTORE_CT \
--rootfs $DATASTORE_CT:15 \
--cores 2 \
--memory 1024 \
--swap 512 \
--password admin \
--net0 name=eth0,bridge=vmbr0,firewall=0,link_down=0,gw=192.168.0.1,ip=192.168.0.220/24,type=veth \
--searchdomain lan.home \
--nameserver 8.8.8.8

Start Container:

pct start $VMID;

Interface eth0 is state anormal !
