Windows Server 2008 R2 is now publically available. Among the new features and many improvements is Hyper-V v2.
Hyper-V v2 supports new features like Live Migration, storage hot-add/remove, Second Level Address Translation, TCP Offloading, VMQ (device queuing), Jumbo frames and processor core parking.
It does however not support the ability to import Virtual Machines from Virtual Server. Therefore I am working on an updated release of the VMC2HV tool with support for Hyper-V v2.
There are other changes and improvements which I will outline once it comes close to release. A screen shot is provided below to give an impression of the new UI.
