HP Integrity Virtual Machines Installation, Configuration, and Administration

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.

7.3.1.3 Guest User
The guest user runs applications on a guest OS. Access is provided and limited by the guest
administrator. There are no Integrity VM storage requirements for application users of the guest
OS.
There are no Integrity VM storage commands for application users in the guest OS. The guest
users use Integrity VM storage on the guest OS the same way as they normally use storage on
an HP Integrity server. Any required Integrity VM storage changes must be directed to the guest
administrator or VM Host administrator.
7.3.2 Integrity VM Storage Use Cases
This subsection describes ways to use the Integrity VM storage commands.
7.3.2.1 Adding Virtual Storage Devices
A VM Host administrator adds or attaches Integrity VM storage using the hpvmstatus and
hpvmmodify commands. Virtual storage devices can be added or attached while the virtual
machine is powered on or off. A new virtual storage adapter can be added only when the virtual
machine is off. The virtual storage adapter can hold up to 15 storage devices and a virtual machine
can use up to 30 storage devices.
The process to add or attach a virtual storage device to a guest is as follows:
1. Based on the all Integrity VM storage considerations, choose a storage device to add.
2. Based on the device type, set up and configure the VM Host to form a valid resource
statement. This includes accounting VM Host resources to avoid future storage conflicts.
3. Use the valid resource statement with the hpvmmodify command to add or attach the
Integrity VM storage device.
