Today kvm-72 was released featuring another merge with qemu-svn, improved windows x64 stability and a change to the qemu window label. The main features from the qemu merge include Virtual Distributed Ethernet (VDE) support and fixes for suspend/resume of multiple nics.

A change you will notice is the annotation of the qemu window which is normally labelled as "QEMU/KVM" to signify that kvm is enabled. This has been removed so that the window is labelled now as just "QEMU". In order to verify that kvm is actually running, an "info kvm" option has been added to the monitor which verifies that kvm "acceleration" is actually enabled. Below shows an example of what you would see when you the issue the info kvm command from within the monitor.

Note the title is now showing "QEMU" also.
