Xen:
        get xen-3.4.2.tar.gz and extract it
        cd xen-3.4.2
        make xen
        make tools
        make stubdom

        and the compiled binaries should be in dist/install/


pv_ops dom0 kernel:

Get Jeremy's pvops dom0 git tree based on instruction here:
http://wiki.xensource.com/xenwiki/XenParavirtOps

And compile it in the normal way:

cd linux-2.6-xen
wget -O .config 
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.4-pvops_dom0-x86_64
(or: wget -O .config 
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31.5-pvops_dom0-x86_32)

make oldconfig
make menuconfig
make bzImage
make modules
make modules_install
cp -a arch/x86/bzImage /boot/vmlinuz-version
cp -a System.map /boot/System.map-version
cp -a .config /boot/config-version

And then create initrd image based on the normal methods in your dom0
distribution.

Edit /boot/grub/grub.conf and you're ready to go.
