kernel git tree
The kvm kernel code is available through a git tree. 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/kvm-userspace.git
Alternatively, it is also accessible through the kernel.org gitweb interface: [2]
linux guest drivers kit
This kit converts a virtio-capable kernel into a package that can generate linux guest drivers for older kernels.
git clone git://git.kernel.org/pub/scm/virt/kvm/kvm-guest-drivers-linux.git
The corresponding kernel tree can found in the virtio branch of kvm.git.
building an external module with older kernels
/!\ This only works for the x86 architecture.
- If you wish to use a distribution kernel (or just some random kernel you like) with kvm,
you can get both the userspace and kernel (via git). In the userspace toplevel directory, type:
./configure [--kerneldir=/path/to/kernel/dir]
- If you are using a released kvm-XX.tar.gz, skip to step 3. If you got the source from git, you need to run the following commands:
cd kernel make sync LINUX=/path/to/kvm/git/tree cd .. make
- Finally, build KVM and the KVM modules:
There are three important directories in this scenario:
| kvm-userspace | Contains a kernel subdirectory. If you got the source from git, it needs to be populated with files from the kvm.git repository (using make sync).
|
|---|---|
| host kernel tree | Older kernel you want to use newer KVM modules with. Refer to it with configure --kerneldir.
You need to point to a configured kernel source tree corresponding to the kernel you are building modules for. The default is to look for the sources of the running kernel at |
| kvm kernel tree (from git) | A clone of the kvm.git repository. Used as the source of the KVM modules. Refer to it with LINUX=path in make sync.

release tags
kvm 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/
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.
