Leave it blank if you want to use phy:.  I myself only use file or lvm 
based vdisks.

If you're using phy:, I guess so!  There's basically three ways of 
sending a vdisk to a guest: physical, lv or file-based.  Note, the 
latter can't be sparse on a netbsd dom0 (vnconfig limitation).

It should be possible, but way more complicated than needed!

Here's a little guide I wrote.  It's assuming a linux dom0 but there 
shouldn't be much difference.  Don't use seek= (sparse files) with dd.
