Microsoft has its desktop virtualization technology, and is up to Version 2 of the Microsoft Desktop Optimization Pack 2009 (MDOP) – the add-on you need for most of the Windows 7 virtualization capabilities – assuming you have the right chip in the first place. The big thing about Windows 7 is that it lets users run their software in XP emulation mode! The App-V (Application Virtualization) client, which is built into MDOP, provides the client side for virtual application launches. Users can click desktop icons to launch a server-based application, which they can use as if it had launched on their own machine. Microsoft Enterprise Desktop Virtualization (MED-V) allows Virtual PC to launch on top of Windows 7 and adds a management capability by linking to Microsoft’s management server and providing the client-side support for policy-based usage controls, provisioning, and delivery of a virtual-desktop image. But enough about that!
Anyway, the new release of z/VM is available only on the IBM System z10 Enterprise Class server and System z10 Business Class server, and future System z servers (z11 and whatever comes next).
According to IBM, z/VM V6.1 offers:
- Guest LAN and Virtual Switch (VSWITCH) exploitation of the Prefetch Data instruction to use new IBM System z10 server cache prefetch capabilities to help improve the performance of guest-to-guest streaming network workloads
- Closer integration with IBM Systems Director by shipping the Manageability Access Point Agent for z/VM to help simplify installation of the agent
- Inclusion of post-z/VM V5.4 enhancements delivered in the IBM service stream.
- z/VM Single System Image:
- z/VM Live Guest Relocation:
IBM intends to provide capabilities that permit multiple z/VM systems to collaborate in order to provide a single system image. This is planned to allow all z/VM member systems to be managed, serviced, and administered as one system across which workloads can be deployed. The single system image is intended to share resources among all member systems.
IBM intends to further strengthen single system image support by providing live guest relocation. This is planned to provide the capability to move a running Linux virtual machine from one single system image member system to another. This is intended to further enhance workload management across a set of z/VM systems and to help clients avoid planned outages for virtual servers.
I’m always interested in VM developments, I wrote two books about VM many years ago, and still have a soft spot for it. It seems that the big daddy of virtualization is still well ahead of any competitors out there and just keeps getting better.
