This release adds support for nested virtualization, a feature which
allows you to run kvm (and possibly other hypervisors) inside a guest.
This is an experimental feature and is only available on AMD hosts.
There are fixes included for a couple of minor vulnerabilities: one for
the slirp stack (-net user), which is not usually used in production,
and another in the vnc server, which allows malicious users to cause a
VM to hang.

the kvm modules provided by Linux 2.6.25 or above. Some features may
only be available in newer releases.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
