LXC network doesn't work after host reboot

[axion.joey]

Hi,

We're testing proxmox 5.2 running the latest enterprise version. We have a few LXC containers running on the hosts and managed through HA. When we reboot a host, all of the containers are started, but their network connections do not work. The only way to re-establish network connection to the containers is to connect to them via the console and reboot them.

Thanks in advance for your help.

I've seen other similar posts, but no one that posted a solution. Is this just a limitation of Proxmox 5?

Mi solucion y como aparece en los post fue colocar en los /etc/apt/sources.list las que corresopondan a la version de proxmox que tengas.
recorda que hay dos maneras

el apt update y apt dist-upgrade
y el apt-get update y apt-get upgrade

actualizas el debian y el pv

espero haberte sido de ayuda
