Today kvm developer Jan Kizka released the latest version of the kvm kernel module. kvm-kmod 2.6.32.7 includes mostly bug fixes against the interface to userspace and also a kernel memory leak fix. Improvements have also been made for packagers of the kernel module. As with all the kvm-kmod releases you can use this to include the latest kernel kvm module features that your current kernel will support even if it is an older version. As usual, to install this module against your current kernel, you simply run configure then make and make install.

Below shows the changelog included with this release:
