NetBSD 5 as DOM0 Howto

First install NetBSD 5 amd64 (with compilers)

Download pkgsrc:
	ftp http://www.llorien.org/NetBSD/pkgsrc-2009Q1.tar.gz

untar pkgsrc in /usr:
	cd /usr
	tar xzf /root/pkgsrc-2009Q1.tar.gz

install xentools33:
	cd /usr/pkgsrc/sysutils/xentools33
	make install clean

install xenkernel33:
	cd /usr/pkgsrc/sysutils/xenkernel33
	make install clean

copy xenkernel to /
	cp /usr/pkg/xen3-kernel/xen.gz /

get Xen DOM0 kernel from installation CD:
	mount -tcd9660 /dev/cd0a /mnt
	cp /mnt/amd64/binary/kernel/netbsd-XEN3_DOM0.gz /
	cd /
	gunzip netbsd-XEN3_DOM0.gz
	umount /mnt
	eject /dev/cd0a

Make Xen bootable by prepending the following line in /boot.cfg:
	menu=Boot Xen with 64MB for dom0:load /netbsd-XEN3_DOM0 console=pc;multiboot /xen.gz dom0_mem=64M
	
start services at boot:
	cp /usr/pkg/share/examples/rc.d/xen* /etc/rc.d/
	echo "xend=YES" >> /etc/rc.conf
	echo "xenbackendd=YES" >> /etc/rc.conf

create the bridge interface (replace bge0 with your external interface):
	echo "create" > /etc/ifconfig.bridge0
	echo "!brconfig \$int add bge0 up" >> /etc/ifconfig.bridge0

reboot and use Xen
