The Virtual network terminal server daemon(vntsd) has provision to configure multiple guest domain consoles using a single TCP port. At the time of domain creation, the LDOM 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. ldm-set-vcons command can be used to bound console to the existing group.
To group the LDOM guest domains console, perform the following steps,
1) Guest domains to be added to the console group should be in inactive state. Use the ldm stop-domain and ldm unbind-domain to make the domains inactive. In this example we will bind the consoles of domains testdom1,2,3 into a single group
primary# ldm stop-domain testdom1
primary# ldm stop-domain testdom2
primary# ldm stop-domain testdom3
primary# ldm list-domain
# ldm list-domain
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME
primary active -n-cv SP 4 1G 0.1% 10d 11h 9m
testdom1 inactive -----
testdom2 inactive -----
testdom3 inactive -----
2) Bind the consoles for the domains into one group primary# ldm set-vcons group0@primary-vcc0 testdom1
primary# ldm set-vcons group0@primary-vcc0 testdom2
primary# ldm set-vcons group0@primary-vcc0 testdom3
3) Bind the assigned resources to the guest domains primary# ldm bind-domain testdom1
primary# ldm bind-domain testdom2
primary# ldm bind-domain testdom3
4) Start the guest domains primary# ldom start-domain testdom1
primary# ldom start-domain testdom2
primary# ldom start-domain testdom3
5) Connect to the associate TCP port of primary-vcc0 console service
primary# telnet localhost 5000
primary-vnts-group0:h, 1, c{id}, n{name}, q:1
