 Introduction

PowerVM compute driver connects to an Integrated Virtualization Manager (IVM) to perform PowerVM Logical Partition (LPAR) deployment and management. The driver supports file-based deployment using images from the OpenStack Image Service.

[Note]Note

Hardware Management Console (HMC) is not yet supported.

For more detailed information about PowerVM Virtualization system, refer to the IBM Redbook publication: IBM PowerVM Virtualization Introduction and Configuration.

 Configuration

To enable the PowerVM compute driver, add the following configuration options /etc/nova/nova.conf:

compute_driver=nova.virt.powervm.PowerVMDriver
powervm_mgr_type=ivm
powervm_mgr=powervm_hostname_or_ip_address
powervm_mgr_user=padmin
powervm_mgr_passwd=padmin_user_password
powervm_img_remote_path=/path/to/remote/image/directory
powervm_img_local_path=/path/to/local/image/directory/on/compute/host

Table 2.25. Description of configuration options for powervm
Configuration option=Default value Description
powervm_img_local_path=/tmp (StrOpt) Local directory to download glance images to. Make sure this path can fit your biggest image in glance
powervm_img_remote_path=/home/padmin (StrOpt) PowerVM image remote path where images will be moved. Make sure this path can fit your biggest image in glance
powervm_mgr=None (StrOpt) PowerVM manager host or ip
powervm_mgr_passwd=None (StrOpt) PowerVM manager user password
powervm_mgr_type=ivm (StrOpt) PowerVM manager type (ivm, hmc)
powervm_mgr_user=None (StrOpt) PowerVM manager user name

 Limitations

PowerVM LPARs names have a limit of 31 characters. Since OpenStack Compute instance names are mapped to LPAR names in Power Systems, make sure instance_name_template config option in nova.conf yields names that have 31 or fewer characters.
