F.3.1 Hypervisor Performance Manager - IBM z13s Technical Manual

F.3.1 Hypervisor Performance Manager

HPM monitors and manages workload performance of the virtual machines under KVM by
performing the following operations:
Detect when a virtual machine is not achieving its goals when it is a member of a
Workload Resource Group.
Determine whether the virtual machine performance can be improved with more
resources.
Project the impact on all virtual machines of the reallocation of resources.
Redistribute processor resources if there is a good trade-off based policy.
F.4 Using IBM Cloud Manager with OpenStack
OpenStack is a cloud-based operating system that controls large pools of compute, storage,
and networking resources throughout a data center and is based on the Open Stack project:
http://www.openstack.org/
IBM Cloud Manager with OpenStack is an advanced management solution that is created
and maintained by IBM and built on OpenStack. IBM Cloud Manager with OpenStack can be
used to get started with a cloud environment and continue to scale with users and workloads,
providing advanced resource management with simplified cloud administration and full
access to OpenStack APIs.
KVM for IBM z Systems compute nodes support these items:
Nova, which is a libvirt driver
Neutron agent for Open vSwitch
Ceilometer support
Cinder support
OpenStack compute node has an abstraction layer for compute drivers to support different
hypervisors, including QEMU and KVM for IBM z through the libvirt API layer (Figure F-4 on
page 519.
