I first used wsl1 and worked fine from the start. Compilation on I/O task (autoconfig task) was slow but all compiled well.
With wsl2 performance are comparable to a native compilation with the confort of use windows while the image compile.
It's like 1 years that is use it and no problem at all.
I did test WSL2 when it came out and it was as fast as setting up a Hyper-V debian box and assigning a vhdx or physical drive to it. That's no surprise, since if you stay on the WSL2 root partition, that's what it is, a tiny hyper-v container.
I switched to VirtualBox, since i can get simple local NAT working, instead of having the default hyper-v switch creeping in every adapter. Than hyper-v is also a L1 hypervisor, so you cant use anything else. Maybe the last point was somehow "fixed" with WSL2?
Not sure. There are other Windows features that rely on virtualization, though, such as the special Edge Sandboxing mode, whose proper name I can't recall right now, and that, too, is supposed to stop other virtualization software from working - at least while active.
The L1 hypervisor Hyper-v uses is a boot feature, either its turned on or off at boot-time. If i check https://docs.microsoft.com/en-us/windows/wsl/wsl2-faq than it seems Vbox6 can optionally be switched to use the hyper-v hypervisor, but no clue what this means for stability/performance. VMware can't at this point so just be aware of the difference in L1 and L2 hypervisors.
about the connectivity... it does still use hyper-v
Also if you want to use vm you need to disable hyper-v and the windows defender virtualization feature. Since they made that difficult to use virtualbox and since i need linux just for the compilation tool, i find the command prompt sufficient, to access wsl2 files you can use a specific path in explorer.
Microsoft changed the rules of game - WS2 .0 is available now in all Windows 10 editiona, including Home edition. I would like to install OpenWRT image on one of non-development machine to investigate some connectivity issues between my Win10 2004 dev pre-view and my router. Is there suitable iSO ?
