Using Console Groups

The virtual network terminal server daemon, vntsd, enables you to provide access for multiple domain consoles using a single TCP port. At the time of domain creation, the Logical Domains Manager assigns a unique TCP port to each console by creating a new default group for that domain's console. The TCP port is then assigned to the console group as opposed to the console itself. The console can be bound to an existing group using the set-vcons subcommand.

How to Combine Multiple Consoles Into One Group

  1. Bind the consoles for the domains into one group.

    The following example shows binding the console for three different domains (ldg1, ldg2, and ldg3) to the same console group (group1).

    primary# ldm set-vcons group=group1 service=primary-vcc0 ldg1
    primary# ldm set-vcons group=group1 service=primary-vcc0 ldg2
    primary# ldm set-vcons group=group1 service=primary-vcc0 ldg3
  2. Connect to the associated TCP port (localhost at port 5000 in this example).
    # telnet localhost 5000
    primary-vnts-group1: h, l, c{id}, n{name}, q:

    You are prompted to select one of the domain consoles.

  3. List the domains within the group by selecting l (list).
    primary-vnts-group1: h, l, c{id}, n{name}, q: l
    DOMAIN ID           DOMAIN NAME                   DOMAIN STATE
    0                   ldg1                          online
    1                   ldg2                          online
    2                   ldg3                          online

    Note - To reassign the console to a different group or vcc instance, the domain must be unbound; that is, it has to be in the inactive state. Refer to the vntsd(8) man page for more information about configuring and using SMF to manage vntsd and using console groups.
