How To Create Ldom In Solaris 11

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.

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. 1.1.1 @(#)Hostconfig 1.1.1 2011/08/03

Hypervisor v. 1.10.1. @(#)Hypervisor 1.10.1.b 2011/09/12

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.

root@labsrv:~# ldm list

NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-c-- UART 64 32256M 0.0% 1d 10h 15m

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.

root@labsrv:~# ldm add-vcc port-range=5000-5100 primary-vcc0 primary

Virtual Disk Service

root@labsrv:~# ldm add-vds primary-vds0 primary

Virtual Switch Service

root@labsrv:~# ldm add-vsw net-dev=net0 primary-vsw0 primary

Verify Changes

root@labsrv:~# ldm list-services primary

Configure the Control Domain

By default we have primary domain, which mean the host operating system.

root@labsrv:~# ldm list

NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-c-- UART 64 32256M 0.0% 1d 30m

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.

root@labsrv:~# ldm start-reconf primary

Initiating a delayed reconfiguration operation on the primary domain. All configuration changes for other domains are disabled until the primary domain reboots, at which time the new configuration for the primary domain will also take effect.

Create alternate configuration file.

root@labsrv:~# ldm add-config primary-config

root@labsrv:~# ldm list-config

factory-default

primary-config [current]

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.

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

root@labsrv:~# ldm list

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

root@labsrv:~# ldm add-vdsdev /rpool/ldoms/OSImages/sol- 11-11.11-sparc.iso solaris11_media@primary-vds0

Create the Logical Domain

root@labsrv:~# ldm add-domain newdom1

root@labsrv:~# 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.

root@labsrv:~# ldm list

NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-cv- UART 4 4G 0.8% 4h 20m

newdom1 inactive ------ 4 4G

root@labsrv:~# ldm bind-domain newdom1

root@labsrv:~# ldm list

NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-cv- UART 4 4G 3.0% 4h 21m

newdom1 bound ------ 5000 4 4G

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 '^]'.

Connecting to console "newdom1" in group "newdom1" ....

Press ~? for control options ..

Start the domain.

root@labsrv:~# ldm start-domain newdom1

LDom newdom1 started
