You can pass zvol entries straight into your zone, but it does require some indirection.  Create a subdirectory from your pool... in my example it's "zvol".  In your zonecfg, have an entry like this:

	add device
	set match=/dev/zvol/dsk/rpool/zvol/*
	end

And you can pass them in directly.

Now this is a more interesting question.  The scope of what LX zones can and cannot do comes into play.

Raw disks in LX zones can probably work with basic read/write ops, but I suspect once you get into ANYTHING mildly tricky with dkio(7I) it breaks down.  A linux app will try ioctls on the raw drives that will return errors because an LX zone still has an illumos kernel underneath at the end of the day.

Before I go down this further, and even suggest you ping another mailing list, I need to know:  What problem are you REALLY trying to solve?  Or why do you need raw disks in an LX zone?

Thanks,
