Required Information

You will need to supply the guest domain information listed below.

name

Name for the guest domain. Each guest domain must have a unique name. This name serves as the label of the guest operating system. The name must be a real hostname for network installations to work.

image location

Location of the installation software. Installation must be over a network (which includes an NFS share from the local host operating system) or be an ISO install.

For example:

--location nfs:my.nfs.server.com:/home/install/test/mydomain

For HVM, an ISO or CDROM device should be given instead of an image location.

Installations using http or ftp, as shown in the following examples, are supported for Linux paravirtualized domain installations only:

http://my.http.server.com:/install/test/mydomain ftp://my.ftp.server.com:/install/test/mydomain

vcpus

The number of CPUs for the guest domain. The default is 1. You can assign specific CPUs. If undefined, the hypervisor makes the selection.

memory

Amount of RAM to be allocated to the guest, in megabytes. A running domain should use a minimum of 512 megabytes. However, to install the guest domain, 1 Gbyte (1024 megabytes) is required.

graphics

Graphical console. Default is graphics. The nographics option applies to paravirtual guests only. If you intend to enable graphics support, you must decide whether the graphical installer should be used.

(Optional) Virtual network interface MAC address

This is the MAC address of the dom0's network interface that you want the domU to use to send and receive internet traffic. By default, the hypervisor tools uses the first available network interface card (NIC) when creating guest domains.

The default values for the action to be taken on a domU shutdown, reboot, or crash are set by virt-install. You currently cannot change these defaults.

The complete list of supported virt-install options are listed in the virt-install(1M) man page.
