Install Solaris 10 in a guest LDOM from CDROM/DVD or ISO

With the release of Solaris 10 5/08 (Update 5) we have the chance to install guest Logical Domains from CDROM/DVD or an ISO image. In the previous releases, the only way to install Solaris 10 in a LDOM was using a Jumpstart Server.
Here we go, fasten your seatbelt ;) :

This is the starting point, three standard services with some values (virtual disk service, virtual console service and virtual network service).
#
ldm ls-services
VDS

NAME VOLUME OPTIONS DEVICE

primary-vds0 vol0 /disco1
VCC
NAME PORT-RANGE

primary-vcc0 5000-5100
VSW
NAME MAC NET-DEV DEVICE MODE

primary-net0 00:14:4f:fb:2b:da e1000g0 switch@0 prog,promisc


#
ldm list-domain
NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME

primary active -n-cv SP 4 1G 8.2% 16h 36m

ldom1 bound —– 5000 4 2G


Now we can start adding some resources to the guest domain we’re creating (CPU and Memory):

# ldm add-domain ldom2
#
ldm add-vcpu 4 ldom2
#
ldm add-memory 4g ldom2

The next commands set up the virtualized network interface and the file that will be used as a virtual disk to install Solaris
#
ldm add-vnet vnet0 primary-net0 ldom2

# mkfile 6g /datos1/disco2
# ldm add-vdiskserverdevice /datos1/disco2 vol1@primary-vds0
# ldm add-vdisk vdisk0 vol1@primary-vds0 ldom2
#
ldm set-variable auto-boot\?=false ldom2

And now the new feature with Solaris 10 U5, we add the ISO image as a virtual device that will be used as the installation media:
#
ldm add-vdiskserverdevice /root/sol-10-u5-ga-sparc-dvd.iso iso@primary-vds0

#
ldm add-vdisk iso iso@primary-vds0 ldom2
– Start of NOTE –
Note: The procedure to install from a CDROM or DVD is the same:
# cdrw -l

# ldm add-vdiskserverdevice /dev/dsk/c0t0d0s2 cdrom@primary-vds0

#
ldm add-vdisk cdrom cdrom@primary-vds0 ldom2
—-End of NOTE—-
Let’s bind and start the new domain:

#
ldm bind-domain ldom2
#
ldm start-domain ldom2
LDom ldom2 started

Press ~? for control options ..


{0} ok show-disks

a) /virtual-devices@100/channel-devices@200/disk@1

b) /virtual-devices@100/channel-devices@200/disk@0

q) NO SELECTION

Enter Selection, q to quit: a

/virtual-devices@100/channel-devices@200/disk@1 has been selected.

Type ^Y ( Control-Y ) to insert it in the command line.

e.g. ok nvalias mydev ^Y

for creating devalias mydev for
/virtual-devices@100/channel-devices@200/disk@1

{0} ok devalias

iso /virtual-devices@100/channel-devices@200/disk@1

vdisk0 /virtual-devices@100/channel-devices@200/disk@0

vnet0 /virtual-devices@100/channel-devices@200/network@0

net /virtual-devices@100/channel-devices@200/network@0

disk /virtual-devices@100/channel-devices@200/disk@0

virtual-console /virtual-devices/console@1

name aliases

We now boot from the virtualized iso image appending the :f (this is to specify the slice 6 of the DVD/ISO image). This can also be done using boot iso:f
{0} ok boot /virtual-devices@100/channel-devices@200/disk@1:f
Boot device: /virtual-devices@100/channel-devices@200/disk@1:f File
