LXC Ubuntu 14.04 template

I was trying to migrate from OVZ to LXC some Ubuntu 14.04 containers. After restore of the dumps, the containers boot, but there is no console output in PVE UI and the network interface doesn't go up. I was thinking it's a problem with the original OVZ container, but the same happen when creating a new container with Ubuntu 14.04. Entering the container using pct form the hardware node and doing ifup on eth0 works, but after reboot the interface is down again.

I am using the laters PVE. The problem is specific to Ubuntu 14.04 only, all the other versions (12.04, 16.04, 18.04) are working as they should... Any idea?

Works for me. Can you post the CT config? `pct config CTID`
Sure, here it is:
root@hn01:~# pct config 116
arch: amd64
cores: 1
hostname: ubuntu.example.com
memory: 1024
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=1A:89:B8:0B:CB:77,ip=,ip6=auto,type=veth
ostype: ubuntu
rootfs: vmdata:116/vm-116-disk-0.raw,size=10G
swap: 512
unprivileged: 1
Looks normal... I can't seem to reproduce this.

Where are you getting the 14.04 template from? I'm using our template and it works.
Can you try the "ubuntu-14.04-standard_14.04.5-1_amd64.tar.gz"? That worked for me.
I re-uploaded that template and tested, with same result. The console show "Connected" message but there's no output. It's quite strange. Also tested, with same result, on two other PVE nodes I have access to. All of them where PVE 5.2 and 5.3 updated to 5.4.
Sometimes the console will get stuck and you can press enter a few times to get it rolling. Did you check if there is network connectivity on the container while the console hangs?
I did press a lot of enter and the cursor go down to next line with no output. The networking interface is not going up. I think it hangs on something during boot way before network setup.

The 118 is an Ubuntu 12.04 container that successfully boot, and 116 is the 14.04. If I "pct enter 116" and run "ifup eth0" then network go up and works still with no output to console, but on reboot it stays down.

It's strange the only problem was with Ubuntu 14.04, but after a reboot looks like everything is working as supposed...
