Code


kernel git tree

The kvm kernel code is available through a git tree (like the kernel itself). To create a repository using git, type

git clone git://git.kernel.org/pub/scm/linux/kernel/git/avi/kvm.git

Alternatively, it is also accessible through the kernel.org gitweb interface: [1]

For subsequent upgrades use the command

git-pull

in the git working dir.

userspace git tree

The kvm userspace code (libkvm and qemu) is available through a git tree. To create a repository using git, type

git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git

Alternatively, it is also accessible through the kernel.org gitweb interface: [2]


building an external module with older kernels

This only works for the x86 architecture.

1. If you wish to use a distribution kernel (or just some random kernel you like) with kvm, you can use the external module kit. You will need the kvm-kmod repository:

git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-kmod.git
cd kvm-kmod
git submodule update --init
./configure [--kerneldir=/path/to/kernel/dir]
make sync
make

Tip about building against Red Hat Enterprise Linux kernels

kvm-userspace/kernel has some compat code to allow it to compile against older kernels, and also some code specific to features that are normally not present on older kernels but are present on RHEL kernels.

So, when building against a RHEL kernel tree, check if the RHEL_* macros at ${kerneldir}/include/linux/version.h are defined correctly, corresponding to the RHEL version where the kernel source comes from. If those macros aren't defined correctly, the compat code that allows compilation against RHEL kernels will break and you will get build errors.


release tags

kvm stable releases (based off of Qemu's stable branch) are tagged with kvm-qemu-0.NN.N where N equates to the upstream Qemu branch versions. Note that kvm has them tagged not branched.

kvm development releases are tagged with kvm-nn where nn is the release number.

Binary Packages

CentOS / RHEL

Unofficial packages of latest releases can be found at: http://www.lfarkas.org/linux/packages/centos/5/

Debian Lenny

There are some updated packages for debian lenny available at: http://www.corpit.ru/debian/tls/kvm/

nightly snapshots

Nightly snapshots, for those who are uncomfortable with git, are available. When reporting a problem with a snapshot, please quote the snapshot name (which includes the date) and the contents of the SOURCES file in the snapshot tarball.
