First have all the build dependencies installed.

Then download the source tree of xen with mercurial

hg clone

or xen-unstable.hg or something.

The various linux dom0 kernels it will download and build are configured in buildconfigs/ and linux-2.6-pvops is the new type of kernel. The default git branch is xen/master which is based on right now but in buildconfigs/mk.linux-2.6-pvops it can be changed to

XEN_LINUX_GIT_REMOTEBRANCH ?= xen/stable-2.6.32.x . 



and it will skip all the configuration questions and you can put in an existing .config in the menu or copying it to ./build-linux-2.6-pvops_x86_64/.config. config- is a .config for the xen/stable-2.6.32.x branch of linux-2.6-pvops.git.

Then any changes to the linux source could be made and run make dist to compile everything.

god dammit, how do I make the firmware?

building a rpm After it is finished compiling, tar -cvzf ~/xendist401rc6pre.tar.gz xen-4.0-testing.hg/dist/ from the parent directory of the source tree with whatever the filename of the tarball should be.

set up the rpm environment

yum install rpmdevtools

build the rpm

To make the rpm from the dist tarball, copy it to ~/rpmbuild/SOURCES/ and edit the spec file in ~/rpmbuild/SPECS/ to have the right version and run rpmbuild -ba prgmrxen4.spec.

cp xendist-luke-mod-1.tar.gz ~/rpmbuild/SOURCES
rpmbuild -ba prgmrxen4.spec

For more information about setting up the rpm build environment see the centos and fedora wikis.
