Hey,
i'm doing a few tests with migrating ovz containers to lxc. Learning about advantages and disadvantages of both.
Here are the instructions that i use to convert the containers: https://pve.proxmox.com/wiki/Convert_OpenVZ_to_LXC
The main point that i struggle is to switch from venets to the eths of lxc.
Running the container with one eth0 and one ip works perfect. But with a second interface eth1 and a second ip there is some routing problem. The second ip is not pingable from outside.
I'm using precreated images from here https://wiki.openvz.org/Download/template/precreated (Ubuntu 12.04 and Ubuntu 14.04)
interfaces inside the container:
auto eth0
iface eth0 inet static
address xx.xx.xx.xx
netmask 255.255.255.255
# --- BEGIN PVE ---
post-up ip route add xx.xx.xx.254 dev eth0
post-up ip route add default via xx.xx.xx.254 dev eth0
pre-down ip route del default via xx.xx.xx.254 dev eth0
pre-down ip route del xx.xx.xx.254 dev eth0
# --- END PVE ---
auto eth1
iface eth1 inet static
address xx.xx.xx.xx
netmask 255.255.255.255
Original templates from lxc don't have that problem. My question - is there any setting inside the container template that forbids the routing to eth1?
Thank you, chris
