😄This artical is just a reminder for myself, not a tutorial. Hopefully it helps you too.

My configuration is as below:

AccessoryType
CPUIntel i7-6700
MOTHERBOARDASUS Z170 Pro Gaming
NET ADAPTERRTL 8125B(with 2 2.5G RJ45)
DISKSQ200EX 480G,PM961A 256G,ZFS:1TB
SYSTEMPVE 7.2-4

The network topology is as below:topology

提示

I've found a repository pve-edge-kernel, it seems to cover configuration and template of LXC openwrt. Anyone interested can hava a try on your own.

Steps

Create the LXC template

Here I used is the slim release of nanopi-openwrt made by klever1988 for that it is simple enough but with the basic extensions installed(e.g. FULLCONE, Argon Theme).

警告

If your PVE lacks FULLCONE, you may need to build it from the source. Here attached the tutorial

Download the firmware you like

cd /var/lib/vz/template/cache/
wget https://github.com/klever1988/nanopi-openwrt/releases/download/2022-07-08/x86-slim.img.gz
提示

If the image you've downloaded is rootfs.tar.gz, you can jump to Create the LXC container.

Mount all the partitions in this raw disk image

kpartx -av x86-slim.img

Under the /dev/mapper, there are 2 loopXpY, one of this contains the Openwrt System.(e.g. loop0p1)

Mount it to path /mnt

mount /dev/mapper/loop0p1 /mnt

Package it to rootfs.tar.gz

tar zcvf openwrt-x86-64-generic-rootfs.tar.gz /mnt/

Unmount

umount /mnt
kpartx -d x86-slim.img

Create the LXC container

PVE CLI Commands

pct create <vmid> <ostemplate> [OPTIONS]
NametypeDescription
vmidinteger(1-N)The (unique) ID of the VM
ostemplatestringThe OS template or backup file (local:vztmpl/openwrt-x86-64-generic-rootfs.tar.gz)
Options
NametypeDescription
--rootfsstorage:disksizeUse volume as container root.
--ostypealpine or debian etc.OS type.
--hostnamestringSet a host name for the container.
--archamd64,arm64,armhf,i386OS architecture type.
--coresinteger(1-8192)The number of cores assigned
--memoryinteger(16-N)Amount of RAM for the VM in MB.
--swapinteger(0-N)Amount of SWAP for the VM in MB.
PCT Commands

The more detailed infomation about PVE is available at PCT-DOCs.

Initialize a LXC container

With the upper commands, we can initialize a container

pct create 100 
local:vztmpl/openwrt-x86-64-generic-rootfs.tar.gz
--rootfs local-lvm:8
--ostype unmanaged
--hostname openwrt
--arch amd64
--cores 4
--memory 1024
--swap 0
-net0 bridge=vmbr1,name=eth1

Modify the configuration of container

Add the content of below:

/etc/pve/lxc/100.conf
# there are some basic configurations in openwrt.common.conf
# which is already existed in PVE system
lxc.include: /usr/share/lxc/config/openwrt.common.conf
# allow /dev/ppp for openwrt dial up with PPPOE protocal
lxc.cgroup.devices.allow: c 108:0 rwm
# assign a specific hookscript
hookscript: local:snippets/hookscript.pl
# Passthrough the physical network card for container
lxc.net.1.type: phys
lxc.net.1.link: enp6s0
lxc.net.1.flags: up
警告

The container will always load the /usr/share/lxc/config/openwrt.common.conf whatever you add it to the configuration of lxc container or not

信息

If you will use openclash in your container or happen to see the error with this format "Unable to set capabilities [sth.] ...", you need to modify the openwrt.common.conf

Comment this 2 lines in below file.([sth.] you lack, and the line where it locates should be commented)

/usr/share/lxc/config/openwrt.common.conf
# lxc.cap.drop is meant to discard some capabilities
lxc.cap.drop = sys_ptrace
lxc.cap.drop = sys_resource

Create the hookscript

Here we used the official example guest-example-hookscript.pl to modify

Create the folder

mkdir /var/lib/vz/snippets

Copy the guest-example-hookscript.pl to the folder

cp /usr/share/pve-docs/examples/guest-example-hookscript.pl /var/lib/vz/snippets/hookscript.pl

Edit this file, you will see the content below at line 36:

/var/lib/vz/snippets/hookscript.pl
    # Second phase 'post-start' will be executed after the guest
# successfully started.

print "$vmid started successfully.\n";

Add the content below to enable TUN and PPPOE:

/var/lib/vz/snippets/hookscript.pl
    # Second phase 'post-start' will be executed after the guest
# successfully started.
system("lxc-device add -n $vmid /dev/ppp");
system("lxc-device add -n $vmid /dev/net/tun");
print "$vmid started successfully.\n";

Start the LXC container

Start the specific container with VMID and then start the LXC terminal

pct start 100
lxc-attach 100

Configure your network

/etc/config/network
config device
option name 'br-lan'
option type 'bridge'
list ports 'eth1'

config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.5'
option netmask '255.255.255.0'

config interface 'wan'
option device 'enp6s0'
option proto 'pppoe'
option username 'xxxxxx'
option password 'xxxxxx'

Restart the network and firewall

/etc/init.d/network restart
/etc/init.d/firewall restart
