[PVE-User] Containers and DHCP

[Alwin Antreich]

Hi Lindsay,

in case you didn't think about this already. ;-)

Are there any container config differences between the ubuntu and the debian containers?

The default timeout and retry for dhclient is 60sec, how long do you wait til you connect to the prompt?

How does your bridge setup (network in general) look like?

auto vmbr0
iface vmbr0 inet manual
        bridge_ports eth3
        bridge_stp off
	# 30sec forward delay is default if fd isn't set to 0
        bridge_fd 0
        bridge_vlan_aware yes


Did you try to set a static IP for the first boot, remove the IP inside the container and run the dhclient manually?
Maybe tcpdump can give you more insight.


== my CT config ==
arch: amd64
cpulimit: 1
cpuunits: 1024
hostname: fs-server.lab.domain.tld
memory: 2048
nameserver: 192.168.2.252 192.168.2.254 192.168.2.14
net0: bridge=vmbr0,hwaddr=62:35:64:65:39:37,ip=dhcp,name=eth0,tag=208,type=veth
onboot: 1
ostype: debian
rootfs: rbd:vm-223250-disk-1,size=8G
searchdomain: lab.domain.tld
swap: 512

Cheers,
Alwin
