Install an OpenWrt KVM on a PVE host machine
Raw
openwrt_pve.md
  1. Install PVE using the official ISO and create a KVM with 512MB of ram and no disk.
  2. In the PVE host shell, run these commands to import the official OpenWrt image into the VM:
cd /tmp
wget https://downloads.openwrt.org/releases/23.05.2/targets/x86/64/openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img.gz
gunzip openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img.gz
# Replace 101 with the VM ID 
qm importdisk 101 openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img local-lvm

Somehow, the official download is extremely slow in Australia. If encounter this case, replace https://downloads.openwrt.org/ in the URL with https://mirror.0x.sg/openwrt/

  1. The first network interface in the OpenWrt VM should be the LAN interface, the second one (If present) will be the WAN interface.
  2. SSH Access: https://gist.github.com/lynus/3446706

Why KVM not LXC?

LXC is not officially supported by OpenWrt, patches and tricks are required.

Why squashfs not ext4?

squashfs is easier to upgrade and factory reset.
