Guest domain is a top level virtual machine which we can create using the control domain. Guest domain will not perform any administrative operation on ldom but runs its own operating system on it.Once you have completed the Oracle VM for SPARC tutorial 1 ,then you can start following this article.We will see how we can create a new guest domain and allocate the resources to it.
Oracle VM for SPARC Tutorial:
[checklist]
- Installation and Configuring the Primary domain
- Creating Guest Domains (You Are Here)
- Configuring I/O Domain
- Dynamically adding/removing Resources
- Live Migration for Guest Domains
- Adding ISO image to Multiple Guests
- Configuration Backup & Restore
- Removing the LDOM and Services
[/checklist]
1. Login to the control domain which we have already configured . (Refer Oracle VM for SPARC tutorial 1 )
2. You need to find out how much resources are available in the system.Use ldm list-devices -a command to get those details.
PD-bash# ldm list-devices -a

7.Now its time to add the new disks to logical domain “ua1” . Here I am using “/dev/dsk/c4t0456RTE000005400002d0s2” LUN for ua1 domain .
8.First i am allocating the LUN to virtual disk server.
PD-bash# ldm add-vdiskserverdevice /dev/dsk/c4t600144F0B8E706DA00005300F4350005d0s2 vol0@primary-vds0

9.Now bind the virtual disk to logical domain “ua1” which you have created in step 8 .

PD-bash# ldm list-bindings ua1

10.The same way you can map the ISO image file to guest domain using the below set of commands.
PD-bash# ldm add-vdiskserverdevice /export/home/sol-10-u10-ga2-sparc-dvd.iso

11.Just bind the logical domain to the primary domain.
PD-bash# ldm list-domain NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 8 4128M 0.4% 26m ua1 inactive ------ 8 4G PD-bash# PD-bash# ldm bind-domain ua1 LDom ua1 started PD-bash# ldm list-domain NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 8 4128M 0.7% 30m ua1 bind ------ 5000 8 4G PD-bash#
12.Set the auto-boot is false to logical domain “ua1” for Operating system installation.
PD-bash# ldm set-variable auto-boot\?=false ua1
13.Boot/start the logical domain “ua1”.
PD-bash# ldm start-domain ua1 LDom ua1 started PD-bash# ldm list-domain NAME STATE FLAGS CONS VCPU MEMORY UTIL UPTIME primary active -n-cv- SP 8 4128M 0.7% 30m ua1 active -t---- 5000 8 4G 12% 1s PD-bash#
14. Take the console of the logical domain “ua1” .It uses the console port 5000 (see step:13)
ok boot iso0
PD-bash# telnet 192.168.2.11 5000
Trying 1192.168.2.11...

15. List the devices to boot.

You have successfully created the guest domain and assigned the resources to it. You have also mapped the virtual disks to the virtualdisk server and mapped to the guest domain or logical domain. In the end of the article ,we have see how to access the console of the guest domains and mapped the ISO file for OS installation.
Hope this article is informative to you .Please share it in social networks. Thank you for visiting UnixArena.

Hi ,
Really this help us lot to create the ldom’s in our environment…
Can you Please brief about LDC in ldom… expecting clear explanation… Thanks in advance
Thanks & Regards,
