Nothing fancy:

wd0e and wd0f are for NetBSD domU, wd0g and wd0h are for a single linux
domU (wd0g root, wd0h swap, but disklabel doesn't know about "linux swap" :)

This is the interesting part :)
The linux install comes from another, working box. On this box, I formatted
wd0g using e2mkfs from sysutils/e2fsprogs and mounted it on the NetBSD
domain0. Then I copied the files from the running linux install,
I don't remember if I used cpio or tar, but you get the idea :)
something like
ssh linux_box 'tar czf - /' | tar xzpf -
