Use the autotest step engine to conveniently install a host kernel, be it an rpm kernel or a git build. Even though this is standard autotest functionality for quite a while, we haven't integrated it properly so far. Now people testing KVM will have a clean, programatic way to test host kernels.
Want to install the kernel from an rpm? Just put it on the control file something like: host_kernel_install = 'rpm' host_kernel_rpm_url = 'http://kojipkgs.fedoraproject.org/packages/kernel/2.6.36/0.32.rc6.git2.fc15/x86_64/kernel-2.6.36-0.32.rc6.git2.fc15.x86_64.rpm' Want to install the kernel from kvm.git, master branch? Just put it on the control file: host_kernel_git_repo = 'git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git' host_kernel_git_branch = 'master' host_kernel_config = 'http://your-server.com/config' You can also specify commits and a list of patches to apply in the kernel before it is built. This change moves the bulk of the KVM test code to a function step_test, and the host kernel install is the implementation of the function step_init(). The interesting variables for the user are defined right at the top of the control file, and, by default no attempt to build/install the host kernel will be made. This change was tested using a fedora box, both kvm.git and a recent fedora rpm kernel were used on a F14 host, but it could use more testing from interested parties, hence I'm putting this here and will wait for comments.
