Compile a Kernel
RHEL 6
Using a kernel source RPM.
# Setup the build environment.
yum -y groupinstall "Development Tools"
yum -y install xmlto elfutils-libelf-devel zlib-devel binutils-devel
# ASCIIdoc needs to be installed from source at the moment.
wget -c http://downloads.sourceforge.net/project/asciidoc/asciidoc/8.6.3/asciidoc-8.6.3.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fasciidoc%2Ffiles%2F&ts=1290017689&use_mirror=superb-sea2
tar -xvzf asciidoc-8.6.3.tar.gz

# Get the src RPM
wget -c http://fedorapeople.org/~myoung/dom0/src/kernel-2.6.32.25-172.xendom0.fc12.src.rpm
# Install the source.
rpm -i kernel-2.6.32.25-172.xendom0.fc12.src.rpm
# Edit the spec file and build (remove the 'asciidoc' requirement as it was fulfilled via tarball).
