Just by installing the kvm package, you can start using kvm, but to implement a deployment, you need a few other packages. Here is what we have in production now. We add these packages using puppet.

• device-mapper-multipath
• libvirt
• kvm
• kvm-kmod^*
• subversion⁺
• virt-manager

With these packages installed, let me tell you about the environment.

^*Local package, we use to contain an updated kvm...when kvm was releasing a new version every week, it was useful to keep the kmod separate.
⁺When is subversion not useful.
