This article mainly shows you "how to install the logical domain in the CMT server and create the guest domain", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to install the logical domain in the CMT server and create the guest domain" this article.

Solution provider preface: by using the commands in this section, you can create, view, install, build network and management logical domains, create guest domains, create virtual machines and install Oracle Solaris 10 systems for users on CMT servers. Logical domain technology enables system administrators to change the CPU and virtual Icano resources of the guest domain, and to clone the system easily.

Install logical domain and create guest domain

How to install logical domains, create guest domains, and install Oracle Solaris systems on CMT servers. The installed domain will be used as the primary mirror for subsequent clones.

Verify and install firmware

All CMT servers and blade modules come with a domain with firmware support logic. However, it is necessary to ensure that * * server firmware is installed and that the installed firmware should match the Solaris version and logical domain management software version in the control domain. You can get the information of * * from http://docs.sun.com. The release notes, reference manuals, and logical domain software management guides list the firmware levels required for each server model. Use the instructions in the server installation guide or administration guide to verify and install the firmware.

Logical domain software installation

The examples in this section are taken from logical domain version 1.2. (note: the file name, command syntax, and screen output may be slightly different from the new version.) you can download logical domain software from http://www.sun.com/servers/ coolthreads/ldoms /. The download file is a zip archive, please use the following command to extract the file (or similar command):

# unzip Ldoms_Manager-1_2.zip

Before installing the software, read the README file in the zip file. This README describes all patches that need to be installed in advance. You can download all the required patches from http://sunsolve.sun.com and install them using the patchadd (1m) command.

At this point, you can run the installation script and respond to any prompts as needed.

You can then verify that the software is installed and that the logical domain daemon is running. Enter the ldm command to access the command line interface. At this point, only one domain is running on the server, which has all installed memory and CPU resources.

The following example comes from a small (6-core) T1000. Each time you run the ldm command, a warning pops up: the system is in configuration mode until the system restarts. For simplicity, we will omit the same warning message later.

Configure the control domain

Initially, the control domain has all the hardware resources, so the resource size of the control domain must be adjusted to provide appropriate memory and CPU resources for the guest domain. Configure basic services such as virtual hard disk, network and console at the same time. When the domain is restarted, the control domain will have the specified number of CPU and memory size. The rest of these hardware resources will be allocated to the guest domain. The command program is similar to the command line shown in the following figure.

Line 1 defines a virtual disk server. Note the naming rules: the name of the server is primary-vds0, primary (control domain) is the name of the domain in which the server resides, and vds0 stands for * virtual disk servers. The * * of this line tells us which domain will run this service. Although it is not necessary to follow this rule, it is recommended that you do so because it enables the service name to have some documentation functionality. In addition, note that the naming convention is independent of the naming of Solaris devices.

Line 2 defines a vcc to listen on local connection ports 5000 to 5100. Line 3 defines a virtual layer 2 switch-- primary-vsw0-- the associated physical NIC device is e1000g0. Multiple virtual switches can be defined and can be attached to different NIC devices or without any devices. Lines 4, 5, and 6 are used to define the control domain: this domain has a single encryption accelerator and four CPU and 3GB memory. The rest of the command line is used to save the initialization configuration to the firmware and restart the server after a current cycle.

The above is all the contents of the article "how to install a logical domain and create a guest domain in a CMT server". Thank you for reading!
