This article focusing on the basic
administration of a Logical Domains environment under Solaris 11 Operating
System. In this article we will go over what it takes to configure a
Solaris 11 installation to be a Logical Domains hypervisor as well as
configuring Logical Domains in order to perform an installation of the
operating system.
Before we start
Check Operating System Version
This is the released version of
Solaris 11 for SPARC, which of course means it can only be used on the SPARC
processor architecture.
root@labsrv:~# uname –a
SunOS t4
5.11 11.0 sun4v sparc sun4v
View Logical Domains Software Version
The release version of Solaris 11 for SPARC comes with Logical Domains
2.1. If you have purchased support and configured access to the
repositories then pkg update will give you access to Logical Domains 2.2.
root@labsrv:~#
ldm -V
Logical Domains Manager (v 2.1.0.4)
Hypervisor control protocol v 1.7
Using Hypervisor MD v 1.3
System PROM:
Hostconfig v.

Hypervisor v.

OpenBoot v.
4.33.1 @(#)OpenBoot 4.33.1 2011/08/03
View Existing Logical Domains
Here we see the specifics of our
physical machine. The primary domain has all of the resources and before
we will be able to allocate resources to other Logical domains we will need to
remove some from the primary domain.

Create Services for Control Domain
Here we are creating the Virtual Console
Concentrator service. This is what allows us to connect to the console
of the domains for installation and reconfiguration.

which mean the host operating system.

We have to reduce the number of vCPU
and Memory from the the control domain to make available to the logical domains.
root@labsrv:~#
ldm set-vcpu 4 primary

root@labsrv:~#
ldm set-memory 4G primary

Reconfigure primary domain to update changes.

Enable the Virtual Network Terminal Server Daemon.
root@labsrv:~#
svcadm enable vntsd
root@labsrv:~#
svcs | grep vntsd
online
13:10:01 svc:/ldoms/vntsd:default
|
Reboot now.
root@labsrv:~#
reboot

After a reboot, make sure the
primary domain must reflect the new memory and vCPU configuration.

Create Install Media Repository
Create a ZFS file system to store
ISO images of Solaris operating system.
root@labsrv:~#
zfs create -p rpool/ldoms/OSImages
|
Add the Solaris iso images to the
Virtual Disk Server service.
root@labsrv:~#
ldm add-vdsdev /rpool/ldoms/OSImages/sol-10-u10-ga2-sparc-dvd.iso
solaris10_media@primary-vds0

Create the Logical Domain
root@labsrv:~#
ldm add-domain newdom1

ldm add-vcpu 4 newdom1
root@labsrv:~#
ldm add-memory 4G newdom1
root@labsrv:~#
ldm add-vnet vnet1 primary-vsw0 newdom1
Add installation media to newly create logical domain
root@labsrv:~#
ldm add-vdisk sol-11-sparc.iso solaris11_media@primary-vds0 newdom1
Configure Virtual Disks
root@labsrv:~#
zfs create -p -V 30G rpool/ldoms/newdom1/disk0
root@labsrv:~#
zfs create -p -V 30G rpool/ldoms/newdom1/disk1
Add Vdisks volumes to the Virtual Disk Server service (pvdisk0).
root@labsrv:~#
ldm add-vdsdev /dev/zvol/dsk/rpool/ldoms/newdom1/disk0 newdom1-disk0@primary-vds0
root@labsrv:~#
ldm add-vdsdev /dev/zvol/dsk/rpool/ldoms/newdom1/disk1 newdom1-disk1@primary-vds0
Assign Virtual Disks to newly created logical domain
root@labsrv:~#
ldm add-vdisk disk0 newdom1-disk0@primary-vds0 newdom1
root@labsrv:~#
ldm add-vdisk disk1 newdom1-disk1@primary-vds0 newdom1
Configure Boot Devices (to autoboot from primary disk0)
root@labsrv:~#
ldm set-var auto-boot\?=true newdom1
root@labsrv:~#
ldm set-var boot-device=disk0 newdom1
|
Set the Host ID
root@labsrv:~#
ldm set-domain hostid=58e92820 newdom1
|
Before we start the logical
domain, we need to bind the associated resources to the logical domain.
This will also show us the port that the console is running on, so that we can
connect to it.

Connect newdom1 prior to starting the domain,
because we prefer to watch the boot up process, so that we know everything is
working properly, this means we will have a separate ssh session which we use
for telnet.
root@labsrv:~#
telnet localhost 5000
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
Connected to t4.
Escape character is '^]'.

Press ~? for control options ..
Start the domain.
