About Network Installations
After you configure the installation server, you can run the virt-install command
from dom0. Use the -d option to add_install_client to specify that the
client use DHCP. If the -d option is not specified, the client uses
bootparams. For xVM paravirtualized guests, both approaches work. Use your site-specific tool for
setting up the appropriate DHCP parameters for the client.
Network Installation
To do a network installation, use the -l option and provide a path
to the network installation image. When giving a machine name or IP address,
the domU must be able to get to that install machine directly, not
go through a router to another net. For example:
-l nfs:install:/export/xvm/xvmgate-70i72-nd
You can also use an IP address instead of a machine name.
For example:
-l nfs:172.20.25.12:/export/xvm/xvmgate-70i72-nd
Example 40-9 Network Installation
virt-install -n gath-01 -r 1000 --nographics -f /dev/dsk/c1t0d0s3 \
-m "aa:04:03:35:a8:06" -p \
-l nfs:install48:/export/xvm/xvmgate-70i72-nd
ISO Image Installation
To use the ISO image, use the -l option with a full path
to the ISO image. If a full path is given instead of
the nfs:mach_name:path format of a network installation, then virt-install assumes that this is
an ISO image:
-l /net/install/export/xvm/solarisdvd.iso
Example 40-10 ISO Image
virt-install -n gath-01 -r 1000 --nographics -f /dev/dsk/c1t0d0s3 \
-m aa:04:03:35:a8:06 -p \
-l /net/install48/export/xvm/solarisdvd.iso
Note - You can quote arguments to options. While arguments, such as the path to
an ISO image, are generally not quoted on the command line, quotes might
be used in scripts.
-l "/net/install48/export/xvm/solarisdvd.iso"
JumpStart Installation
JumpStart configuration files are manually created and managed. You can initiate a custom
JumpStart through network installation after setting up the server. When you create a
profile server, you must ensure that systems can access the JumpStart directory on
the profile server during a custom JumpStart installation. Each time that you add
a system for network installation, use the add_install_client command to specify the profile
server. You use the add_install_client command to create the /etc/bootparams entry for the
domU.
To do a JumpStart with virt-install, use the --autocf option. For example:
--autocf nfs:install:/export/jumpstart/jump-user/x86
You cannot use a full path such as:
--autocf /net/install/export/jumpstart/jump-user/x86
Example 40-11 JumpStart
virt-install -n gath-01 -r 1000 --nographics -f /dev/dsk/c1t0d0s3 \
-m aa:04:03:35:a8:06 -p \
-l /net/install48/export/xvm/xvmgate-70i72/solarisdvd.iso
--autocf nfs:install:/export/jumpstart/jump-user/x86
