If it helps, I'm currently running a Windows kvm guest that runs WSL2, but I had to change my processor type.

Ubuntu 22.04 Host, virt-manager/ qemu/ kvm hypervisor Win10x64 Guest, CPU model is set to "Broadwell-noTSX-IBRS"

It's definitely not as performant with this setting, but it gets the job done so I can run WSL2 and Docker Desktop in my Windows vm.

YMMV.
