Introduction Ignite-UX makes it easier than ever to deploy Integrity Virtual Machines (Integrity VM) product on an Itanium-based server. Once the virtual machine is created, installation of the HP-UX operating system and software on the virtual machine (VM) is made easy through the use of Ignite-UX. Generally speaking, the use of Ignite with Integrity Virtual Machines is no different from that of a physical Integrity server.

This example indicates that the VM myvm02 is connected to the virtual switch vswA. In the event no such entry exists for the VM, then a virtual network connection must be defined. To create such a connection, use the hpvmmodify command as follows: # hpvmmodify –P myvm02 –a network:lan::vswitch:vswA Note that the MAC address will not match that shown in this example as Integrity VM will automatically generate a MAC address for the virtual LAN.

To do this, first power on the VM (e.g.

Advanced Network Installation When deploying several virtual machines, it can be cumbersome to repeatedly configure the operating system and software for each new virtual machine. Ignite-UX provides a means to dramatically simplify that process. Creating a VM configuration for repeated use with Ignite-UX If you are in a position where you are or will be installing the same operating system and software configuration on multiple VM systems, it may be prudent to create a golden image.
PAGE 10
Installing Integrity VM guest software The HPVM-Guest bundle should be considered when creating an Integrity VM golden system. This bundle tunes the HP-UX operating system for operation on a VM and also includes commands for collecting status and state of a VM as well as managing it. The dynamic memory control device driver is also included in this bundle and care must be taken to make sure golden images have this device driver configured correctly when the bundle is installed on the golden system.

Figure 6 - Selecting the new VM configuration for installation Using Virtual DVD with ISO Images Integrity Virtual Machines have a unique use for golden images in that they may be converted into ISO images which can be used as virtual DVDs. To do this, the golden system is set up as discussed in the Preparing a system to be a golden image section above. This system is used to create an ISO image which is then mapped to virtual DVDs for one or more VMs.

Figure 7 - Virtual console showing automatic boot from virtual DVD (ISO image) Sharing media among virtual machines Once you have the ISO image on the Integrity VM Host, you may want to use it with multiple VMs to start the installation process. As before, the virtual DVD must be defined for the new VM. For example: # hpvmmodify -P vm12 -a dvd:scsi::file:/hpvm/ISO/B.11.23.iso When doing so, you may receive messages similar to the following: hpvmmodify: ERROR (vm12): Duplicate backing device /hpvm/ISO/B.11.

Ignite-UX and the Integrity VM Host Creating a VM Host golden image Typically, the need for a golden image is associated with virtual machines that are being deployed, rather than the Integrity VM host itself. The steps above can be used to create a golden image of any configuration including one for an Integrity VM host. For example, there may be a standard set of management tools and system software that is used to manage and monitor an Integrity VM host.
PAGE 14
Appendix A – Creating and Configuring a Golden Image for Network Installation Making the operating system archive Once the golden system is configured the way you want it, either install the Ignite-UX software or copy the file /opt/ignite/data/scripts/make_sys_image to /tmp on the golden system. If you’ve copied the above file, change the permissions of /tmp/make_sys_image to be executable.
PAGE 15
Configuring the Ignite-UX server to recognize the golden image Once the golden image has been created, you’ll need to finish setting up the configuration for use on the Ignite-UX server. The steps to do this are as follows: 1. Capture the necessary impacts statements to be used in the configuration file by executing: # /opt/ignite/lbin/archive_impact -t -g B.11.23_VM_archive.gz in the directory where the archive was created and capturing the output.
PAGE 16
c) Replace the ‘impacts’ lines with those captured in step 1 above.

5. Edit the file /var/opt/ignite/INDEX to install the new configuration for Ignite-UX. This is done by adding a new cfg section to that file. For our example, the new cfg section would read as follows: cfg "HP-UX B.11.23 VM Config" { description "This selection supplies the VM configuration." "/opt/ignite/data/Rel_B.11.23/config" "/var/opt/ignite/data/Rel_B.11.23/vm.cfg" "/var/opt/ignite/config.local" } 6.
PAGE 18
# cp –p /opt/ignite/data/examples/B.11.23.archives.cfg \ /scratch/staging/vm.cfg You’ll need to customize the configuration file for your archive. Two modifications of the (is_ia64) section are necessary. First, change the archive_path so that it reflects the path of the operating system archive file. For example, in the vm.cfg file, change: archive_path = "data/B.11.23_archive_IA.gz" to: archive_path = "./vm.
PAGE 19
Copying the EFI image Itanium-based systems, including Integrity VMs, require an EFI image. Thus, the EFI image must be copied to the directory where the ISO image is being staged: # cp -p /opt/ignite/boot/Rel_B.11.23/EFI_CD_image /scratch/staging/ Creating the ISO image Now that everything is in place, the ISO image is created with the mkisofs command. Note that we use the Itaniumbased variation of this command.
PAGE 20
Moving the ISO image to the Integrity VM Host Once you’ve verified it to be a valid LIF image, move it to the Integrity VM Host by whatever means is most efficient in your environment (for example, using ftp). A final note with regard to creating ISO images from golden images larger than 2GB - version C.6.5.61 or later of IgniteUX is required.
