I just got this working in windows preview build too. If you enable KVM and rebuild the WSL2 kernel, then you can follow the Linux firecracker demo on github step by step and it works. I was able to launch 400 concurrent firecracker VMs on my laptop in 60 sec.

60s total or each? I haven't tried WSL2 but I had to help people with _really_ bad docker performance running in WSL (php page load took around 60s)

Total. And it was like the first 200 were in 15 to 20 sec.
