When you install Integrity VM, the VM Host is automatically created
and started. The resources of the VM Host system can be allocated to the guests,
but the VM Host requires certain dedicated resources as well. Therefore, in
order to install Integrity VM and the guests, you must understand what resources
the VM Host system offers and what resources must be restricted to use by
the VM Host. Table 2–1 describes the
VM Host system resources, including those that must be restricted to the VM
Host and those that can be allocated to guests. This table includes an example
VM Host system, which is used later in the discussion of how to plan the guests.
Table 2-1 VM Host System Resources Information
| System Element | Description | Example |
| VM Host name | The name of the VM Host system. It is generated from the UNIX system
name. | compass |
| Operating system | The operating system running on the VM Host. You can run HP-UX 11i
v2 May 2005 or later. | HP-UX 11i v2 May 2005 |
| Number of physical CPUs | The number of physical CPUs on the VM Host system. | 4 |
| Memory (RAM) | The amount of memory on the VM Host system. | 32 GB |
| Reserved memory | The amount of memory that is reserved for the use of the VM Host. Refer
to “Installation Requirements” in
Chapter 3. | 5 GB |
| Network adapters | The number of network adapters (also called NICs, or network cards)
on the VM Host system. | 2 |
| IP addresses or DHCP | The IP address for each network adapter, or served by a DHCP server. | lan0: 17.22.3.4 lan1: DHCP |
| Boot device | The VM Host system's boot device. This device must not be accessible
to guests. | /dev/rdsk/c0t1d0 |
| Unique UNIX account name | The UNIX account name for the VM Host system administrator. | hostadmin |
| Restricted devices | The devices that must not be accessible to guests. These include the
boot device, the swap device, and any logical volumes used by the VM Host.
Network devices can also be restricted to the VM Host. For more information,
refer to “Restricting Devices to the
VM Host” in Chapter 3. | /dev/vg00/lvol3 |
After you have recorded the information about the VM Host requirements
and characteristics, you should plan each guest's requirements and characteristics
to ensure that the virtual machines run as efficiently as possible without
contending for resources on the VM Host system.
