Once correctly configured, the pool can be set to start automatically upon booting of the host:

# virsh pool-autostart kvmguest

Pool kvmguest marked as autostarted

The virt-install command can be used to install new guests from the command line. The

--disk argument can take the name of a storage pool, followed by the name of any contained

volumes. Continuing this example, the following command will begin the installation of a

guest with two disks; the first disk is the root file system, the second disk can be shared

between multiple guests for common data:

# virt-install --accelerate --name rhelx86_64 --ram 800 --vnc --disk \

vol=kvmguest/10.0.0.1 --disk vol=kvmguest/10.0.0.2,perms=sh --pxe

Once this rh elx86 _6 4 guest is installed, the following command and output shows the XML

that virt-install used to associate the guest with the iSCSI LUNs:

# virsh dumpxml rhelx86_64

<name>rhelx86_64</name>
