Host ID Emulation

When applications are migrated from a standalone Solaris 9 system into a solaris9 zone on a new system, the hostid changes to be the hostid of the new machine.

In some cases, applications depend on the original hostid, and it is not possible to update the application configuration. In these cases, the solaris9 zone can be configured to use the hostid of the original system. This is done by setting a zonecfg attribute to specify the hostid, as shown in How to Configure a solaris9 Branded Zone. The value used should be the output of the hostid command as run on the original system. To view the hostid in an installed zone, also use the hostid command.
