HP Integrity Virtual Machines Installation, Configuration, and Administration Version A.03.50

7.3.1.1 VM Host Administrator
The VM Host administrator role is an individual responsible for the proper configuration and
maintenance of the VM Host for running virtual machines. As such, this person needs complete
access to the VM Host to install hardware and software. This person also needs to understand
how to do HP-UX system maintenance, how to configure hardware properly, and how to set up
and use various software applications and tools.
The VM Host administrator uses the following commands to manage virtual machine storage
devices:
Integrity VM CommandManagement Function
hpvmmodify (see Section 3.4: “Changing Virtual Machine
Configurations” (page 41))
Add, delete, manage, and modify virtual machine storage
devices
hpvmstatus (see Section 9.1: “Monitoring Guests”
(page 123))
Display information about the storage devices for a virtual
machine.
Once a resource is added or attached to a virtual machine and the virtual machine is powered
on, the storage resource is owned by the guest administrator. That is, the guest OS may access
that storage resource at any time. A deletion, detachment or modification fails if any guest I/O
is active on the resource. Dynamic storage changes on an active virtual machine must be approved
by the guest administrator.
7.3.1.2 Guest Administrator
The VM Guest Administrator is responsible for the proper maintenance of a guest OS. As such,
this person needs access to the virtual console by the VM Host administrator to control the virtual
machine. The guest administrator must understand how to maintain the guest OS, install patches
and applications, and set up security for the guest users of the guest OS. Additionally, Integrity
VM storage requires you to:
• Install any specific guest OS patches required by Integrity VM for proper OS operation on
the virtual platform.
• Review and understand any Integrity VM storage release notes that are specific to the guest
OS.
• Work with the VM Host administrator to complete virtual storage changes, including
managing attached VM Host devices.
The guest administrator uses the virtual console to modify virtual storage. The virtual console
is used to change discs of a virtual DVD device type. All modifications are bounded by what the
VM Host administrator configures for the virtual machine.
The virtual console commands are available from the vMP Main Menu, using the hpvmconsole
command or by pressing Ctrl/B if you are already connected . The virtual console commands
eject (ej) and insert (in) allow you to control the DVD device. Both commands provide submenus
for displaying devices that are removable. Selecting options through the submenus completes
the ejection/insertion process.

OS.
