HP vPars and Integrity Virtual Machines V6.1 Administrator Guide

7 Creating virtual machines
After you install the vPars and Integrity VM product, you can create virtual machines and virtual
resources for the virtual machines to use. This chapter includes the following topics:
• Specifying VM characteristics
• Using the hpvmcreate command
• Starting VMs
• Changing VMs configurations
• Cloning VMs
• Stopping VMs
• Removing VMs
• Troubleshooting virtual machine creation problems
7.1 Specifying virtual machine characteristics
When you create a new virtual machine, you specify its characteristics. Later, you can change the
virtual machine characteristics.
You can set the characteristics of a virtual machine using the following commands:
• hpvmcreate, which creates new virtual machines.
• hpvmclone, which creates new virtual machines based on existing virtual machine.
• hpvmmigrate, which moves virtual machines from one system to another.
• hpvmmodify, which modifies existing virtual machiness.
All of these commands accept the same options for specifying VM characteristics. Table 11 describes
each characteristic and command option.
