Follow this guide to install and configure libvirt on Debian, add a user to the libvirt group, and set up an OpenWRT VM using libvirtd. which allows both debain and openwrt use simultaneously.
The graph shows the idea of how it is running and may have some difference between this wiki and graph.
Debian will have full USB Wifi and 5G USB Modem Access.
Install libvirtd in Debian
Install libvirtd using APT (require root privilege):
apt-get install libvirt-daemon libvirt-clients bridge-utils
Add user to libvirtd
This operation require root privilege.
#Replace photonicat to your user name if you changed user name. usermod -a -G libvirt photonicat
Then reboot to apply changes.
Example: Run OpenWRT on libvirtd
The operations below require root privilege.
Setup Network
Add bridge configurations below to /etc/network/interfaces:
iface eth0 inet manual iface eth1 inet manual auto br-wan iface br-wan inet dhcp bridge_ports eth0 bridge_fd 0 auto br-lan iface br-lan inet static bridge_ports eth1 address 172.16.0.2 netmask 255.255.255.0 bridge_fd 0
Then reboot to apply changes.
Prepare kernel & rootfs image
mkdir -p /var/lib/libvirt/boot/openwrt cd /var/lib/libvirt/boot/openwrt wget https://downloads.openwrt.org/releases/23.05.5/targets/armsr/armv8/openwrt-23.05.5-armsr-armv8-generic-kernel.bin wget https://downloads.openwrt.org/releases/23.05.5/targets/armsr/armv8/openwrt-23.05.5-armsr-armv8-generic-initramfs-kernel.bin cd /var/lib/libvirt/images wget https://downloads.openwrt.org/releases/23.05.5/targets/armsr/armv8/openwrt-23.05.5-armsr-armv8-generic-ext4-rootfs.img.gz gunzip openwrt-23.05.5-armsr-armv8-generic-ext4-rootfs.img.gz
Setup VM
Create file /tmp/openwrt.xml with contents below:

Import VM:
virsh connect qemu:///system create /tmp/openwrt.xml
Setup Guest
Use virt-manager or other frontend to login VM, set eth1 to 172.16.0.1. Access OpenWRT with 172.16.0.1 by SSH or browser.
Change VM configuration
virsh connect qemu:///system edit OpenWRT
Change system disk
If you want to change system disk image, an ext4 filesystem with or without partition image:
<source file='/var/lib/libvirt/images/openwrt-23.05.5-armsr-armv8-generic-ext4-rootfs.img' index='1'/>
Change file property to the system disk image you want.
If your system disk image is just a filesystem image (no partition table), set cmdline section to root=fe00: (like the one you downloaded: https://downloads.openwrt.org/releases/23.05.5/targets/armsr/armv8/openwrt-23.05.5-armsr-armv8-generic-ext4-rootfs.img.gz)
<cmdline>root=fe00</cmdline>
If your system disk image has a partition table, you should set cmdline section to setup rootfs device (e.g: /dev/vda1):
<cmdline>root=/dev/vda1</cmdline>
