Once you've issued the ldm commands needed to define domain ldom2 , you can
simply bind and boot the guest domain—Oracle Solaris is already installed on the
virtual disk.
A cloned Solaris instance has the same IP address and host name as the sys-
tem it was cloned from. You can choose from several methods to give it a unique
identity. One strategy is to configure the guest to use DHCP at boot. Another tech-
nique is to issue the /usr/sbin/sys-unconfig command before shutting down
and cloning the golden image. The first boot of the cloned image will then prompt
(at the guest console) for system identification data, such as the time zone, IP ad-
dress, and so on. Alternatively, you can configure the golden image domain with a
unique host name and IP address that will not be given to any other domain. After
booting a domain cloned from it, simply log into the clone via SSH, and change
its host name and IP address via standard Solaris administrator commands. An
advantage of this method is that it avoids the use of the guest console.
3.5 Domain Mobility
Domains can be installed on one CMT server (the source host) and migrated to a
different, compatible CMT server (the target host) for planned workload migra-
tion. Doing so can free up memory and CPUs on a server, or vacate it for planned
maintenance. At the time of this writing, Logical Domains supported two forms
of domain migration, both invoked by the ldm migrate command. The following
command migrates a domain to the host at the specified address. The command
will prompt for the root password of the control domain on the target system.
