-1.0.0
-=====
-
-*nova-dpm* 1.0.0 is the first release of the Nova virtualization
-driver for the PR/SM hypervisor of IBM z Systems and IBM LinuxOne
-machines that are in the DPM (Dynamic Partition Manager)
-administrative mode.
-
-New Features
-------------
-
-* Configure a compute node to manage and consume only
-  a subset of a *z Systems* CPC in DPM mode.
-* CPC subsetting is hidden from users and they are treated
-  like normal hosts in OpenStack.
-* Spawn instance from FCP volume.
-* Instance lifecycle management.
-* Use flat networking.
-
-Known Issues
-------------
-
-* VLAN and tunneled networks are not supported in this release.
-* Cinder driver for Storwize V7000 Unified returns additional WWPN's
-  which are tagged as NAS, which are used for internal connections.
-  The invalid target WWPN's need to be blacklisted in nova
-  configuration parameters.
-* Fibre Channel Multipathing is not supported.
-* The configuration parameter ``[DEFAULT].host`` cannot be more than
-  17 characters in length.
-* Networking: 12 ports per partition at the maximum.
-* Networking: In the guest image, always port 0 of an network adapter gets
-  autoconfigured. If port 1 should be used, manually deconfigure port 0 and
-  configure port 1 in the operating system of the launched instance.
-* Boot from image is not available. Boot from volume has to be used.
-* Only a single fibre channel network is supported. Configured storage
-  adapters and cinder fibre channel backends must all use the same fibre
-  channel network.
-* The configured maximum number of partitions (``[dpm].max_instances``)
-  is not yet enforced.
-* All bug reports are listed at: https://bugs.launchpad.net/nova-dpm
