The main difference between WSL1 and WSL2 that later is hyper-v based Microsoft Linux version, it sounds like excited news at least it is running full Linux kernel but there are too many issues if use as devops box.
Here are some examples:
- WSL2 ip dynamic assigned after reboot, so it is not static ip, will give trouble for app like k8s api server
- WSL2 uses own boot system so systemd not run as default even it exists
install WSL2 Ubuntu

remedy for "static" ip
WSL2 Set static ip? · Issue #4210 · microsoft/WSL · GitHub
Assume we want to keep static ip 192.168.80.2 for WSL2 Ubuntu, run below batch script as Administrator on windows host, you can type wsl2ip.bat from CMD, PS or place shortcut icon on desktop. It re-create eth0 with static ip, update routing, nameserver and re-create adapter vEthernet for WSL, also change to NAT.
C:\Users\oldhorse>type wsl2ip.bat
date /t
time /t
wsl -d Ubuntu-20.04 -u root ip addr del $(ip addr show eth0 ^| grep 'inet\b' ^| awk '{print $2}' ^| head -n 1) dev eth0
wsl -d Ubuntu-20.04 -u root ip addr add 192.168.80.2/24 broadcast 192.168.80.255 dev eth0
wsl -d Ubuntu-20.04 -u root ip route add 0.0.0.0/0 via 192.168.80.1 dev eth0
wsl -d Ubuntu-20.04 -u root echo nameserver 192.168.80.1 ^> /etc/resolv.conf

shutdown WSL2 and apply static ip script before reboot,
wsl --shutdown .\wsl2ip.bat will see systemctl is working now.

I uninstall Docker for Desktop on WSL2 however I keep docker.exe, kubectl.exe windows client in someplace, as test to run them with WSL2 native k8s cluster, it is working fine as portable tools.

Vagrant
Installed vagrant on WSL2 is not problem but didn’t see any point to run native vagrant from WSL2 since real work still needs vagrant on win11 Host to communicate with hypervisor Virtualbox or Hyper-V.
We can run vagrant.exe from both cmd/PS and WSL2 smoothly.
pre setup, allow access vagrant and hyper-v on windows from WSL2,
export VAGRANT_WSL_ENABLE_WINDOWS_ACCESS="1" export PATH="$PATH:/mnt/c/Program Files/Hyper-V" ln -s /mnt/c/Users/oldhorse/vagrant ~/vagrant
verify windows vagrant ready,
Windows vagrant C:\Users\oldhorse>where vagrant C:\HashiCorp\Vagrant\bin\vagrant.exe C:\Users\oldhorse>vagrant -v Vagrant 2.2.18
build a ubuntu vm in hyper-v using vagrant,
C:\Users\oldhorse\vagrant\master\Vagrantfile
Vagrant.configure("2") do |config|
config.vm.box = "generic/ubuntu1804"
config.vm.define "master" do |master|
master.vm.hostname = "master"
master.vm.provider "hyperv" do |v|
v.memory=1024
v.cpus=1
end
end
end
