virtio?

[cerebrate]

Does anyone have a pointer to a explanation of the virtio/virtio9p/virtiofs options and their prerequisites? I'm feeling the urge to experiment, but I can't find a useful amount of detail on them in any one spot.

Maybe this, at least for virtiofs? https://www.boxofcables.dev/wsl2-per-device-swiotlb-pools-for-virtiofs-and-virtioproxy/

That one I found. 😁

That article was what sent me down this path in the first place, but since enabling virtiofs for me just leaves me without /mnt/c working at all (no mount there, period), I was hoping for something with a little more detail.

@cerebrate .
The virtio9p option is a null option. It's force-disabled in code.

WSL/src/windows/common/WslCoreConfig.cpp

Lines 452 to 456 in 9eeea1a

	if (EnableVirtio9p)
	{
	EMIT_USER_WARNING(wsl::shared::Localization::MessageConfigVirtio9pDisabled());
	EnableVirtio9p = false;
	}

The virtio option controls other virtio dependent features. It's default to on when possible. And should not be modified.
