HP Integrity Virtual Machines 4.3: Installation, Configuration, Administration

the associated guest with the usermod command. This allows multiple accounts to map to the
guest, and requires the account names to be valid HP-UX login strings.
Authorization of access to the virtual console is determined by the guest configuration file (set
using the -u and -g options to the hpvmcreate, hpvmmodify, and hpvmclone commands).
This controlled access allows you to temporarily block access by using the hpvmmodify command
to change the virtual console administrator account name.
8.5.2 Guest User Accounts
The configuration for captive hpvmconsole guest user accounts has changed in Integrity VM
Version 4.0 and later to support additional access controls and configurations. This change
requires that the guest user accounts have the correct home directory. It is also necessary to list
the console access account in the guest configuration file.
For example, using a guest named compass1 (and therefore a user account named compass1),
the home directory for user compass1 must be /var/opt/hpvm/guests/compass1. To
ensure that the user continues to have administrative console access, use the following command:
# hpvmmodify -P compass1 -u compass1:admin
8.6 Installing the Guest Management Software
After you install the guest OS, you must install special Integrity VM guest management software.
Installing the guest management software on each guest provides patches for performance
improvements and allows you to use Integrity VM command on the guest. Without the guest
management software, you cannot use guest dynamic memory. And, with the latest guest
management software, the guest can be managed by VM Manager and the ID-VSE products.
Figure 8-1 illustrates the process. Guest management software is copied onto the VM Host system
when you install Integrity VM. When you upgrade to a new version of Integrity VM, the guest
management software is also upgraded in the VM Host guest management software repository.
You manually install the appropriate guest management software on each guest, depending on
the guest OS.

The guest management software is required on each guest. The guest management software
ensures that guests have the required patches for optimum performance and manageability. It
also enables the hpvmmgmt, hpvmcollect, and hpvminfo commands on the guests, as
appropriate. (Not all commands run on all types of guests.) It also provides support for the VM
Host's hpvmsar command.
The guest management software is stored on the VM Host system in the /opt/hpvm/
guest-images directory. A subdirectory contains the guest management software for each
type of guest operating system, as shown in the following example:
