Install PowerKVM
----------------
The process to set up PowerKVM hypervisor with xCAT is the same with Diskfull installation. Prepare powerKVM iso, such as ibm-powerkvm-2.1.1.0-22.0-ppc64-gold-201410191558.iso, then refer to :ref:`diskful_installation` to install PowerKVM hypervisor.
The process to set up PowerKVM hypervisors using xCAT is very similar to deploying diskful compute nodes.
#. Download the PowerKVM iso and add it to xCAT using copycds: ::
# if the iso file is: ibm-powerkvm-2.1.1.0-22.0-ppc64-gold-201410191558.iso
copycds -n pkvm2.1.1 ibm-powerkvm-2.1.1.0-22.0-ppc64-gold-201410191558.iso
#. Then provision the target node using the PowerKVM osimage: ::
nodeset <noderange> osimage=pkvm2.1.1-ppc64-install-compute
rsetboot <noderange> net
rpower <noderange> reset
Refer to :doc:`/guides/admin-guides/manage_clusters/ppc64le/diskful/index` if you need more information.
Verifying hypervisor bridges
----------------------------
After PowerKVM hypervisor is installed successfully, you can get the bridge information by running ``brctl show``: ::
In order to launch VMs, bridges must be configured on the PowerKVM hypervisors for the Virtual Machines to utilize.
# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000000000000 no eth0
Check that at least one bridge is configured and mapped to a physical interface. Show the bridge information using ``brctl show``: ::
# brctl show
bridge name bridge id STP enabled interfaces
br0 8000.000000000000 no eth0
If there are no bridges configured, the xCAT post install script will not work. You must manually create a bridge. The following is provided as an example for creating a bridge br0 using interface eth0 with IP address: 10.1.101.1/16, for example: ::
