What is the suggested method of creating a NetBSD domain?

What userland tools are needed?

Is the only code outside of the NetBSD source tree needed Twisted?

My thoughts on doing this were to 1) Install NetBSD-2.0 snapshot directly on dedicated partition. Copy in Xen kernel.

2) create filesystem images on an NetBSD/i386 machine and dd image into a dedicated partion (Has anyone tried this using LVM). My worries are in getting the disk label information correct.

3) Cross compile NetBSD userland on Xen/Linux machine. Use cross-compiled disklabel/mkfs to create NetBSD filesystem.

Have the Xen NetBSD patches been merged back into the NetBSD tree? What is the suggested NetBSD userland (NetBSD 2.0 RC4)?
