Can't, system reboots immediately after the loading of xen.gz. Here is the uname -a output when booted in i386 mode with generic kernel:

NetBSD 3.0 NetBSD 3.0 (GENERIC) #0: Mon Dec 19 01:04:02 UTC 2005 i386

the xen.gz kernel does not work on a Via Technologies C3 chipset.
I followed the directions in the Xen HOWTO to setup a domain0 on a via technologies PD6000 mini-itx board, including the installation of GRUB.

After the system loads xen.gz, the system immediately reboots. I can't even read the error message.

I followed the same procedure documented in the Xen HOWTO on an intel pentium4 setup, and had 0 issues getting domain0 to boot, so I do not think it is an installer issue (ie me installing it wrong or missing a config in the grub menu.lst file)

I found this on the xen-devel mailing list via google:

that seems to document a similar problem.

Install NetBSD3.0, then install domain0 as documented by the xen HOWTO on a via technologies board that has a C3 chipset. The system will immediately reboot. I can arrange access to the system remotely with serial console if someone would like to look at it further. I can be contacted at
