Today, IBM announced a
preview of z/VM Version 6 Release 1
(V6.1), the newest version of z/VM that is intended to be the base for
all future z/VM enhancements. z/VM V6 requires
a new architectural level available only on IBM
System z10 servers or later. z/VM V6.1 is also designed to offer:
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
- 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
This release provides the basis for some major future enhancements as
indicated by the announced Statements of Direction* that include:
- z/VM Single System Image:
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
- z/VM Live Guest Relocation:
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.
It was important to deliver a new z/VM release as a mechanism to set the
stage for these planned future enhancements.
The virtualization technology provided by z/VM and the IBM System z
platform is a cornerstone and key enabler for building a dynamic
infrastructure and may help clients achieve operational goals of high
availability, business resilience, improved speed-to-market,
better resource control and reporting, and the flexibility to expand and
contract system resources with changing business demands.
More specific details regarding z/VM V6.1 will be forthcoming in the
fourth quarter of 2009.
