PVE 4.3 - Debian 7 container not booting

[Glenn]

Dear Proxmox Community Members,

There seems to be an issue with PVE 4.3 and LXC container with Debian 7. When connecting to the terminal using NoVNC or using "lxc-consol -n 102" I'm just getting a black screen.

I can't find the root cause and hoping to get a direction to solve this issue.

LXC Template: debian-7.0-standard_7.0-3_amd64.tar.gz
Kernel Version: Linux 4.4.19-1-pve #1 SMP Wed Sep 14 14:33:50 CEST 2016
PVE Manager Version: pve-manager/4.3-1/e7cdc165
