The experiment manages Hypervisor, host aggregation, specification key pairs, and VM group testing through openstack dashboard and openstack CLI, and tests VM provisioning, lifecycle management, snapshots, and rebuilds.

Openstack Dashboard Operations Hypervisor and Host Aggregation Management

Host aggregation divides the available area into logical units by grouping hosts together. Create a host aggregation and select the hosts you want to put in it.

Log in to the Openstack Dashboard interface using admin. Select "Administrator-Compute-Virtual Machine Manager" in the navigation bar to enter the virtual machine list and view information such as hypervsior overview.

Select Compute Hosts to include them in the Compute Hosts list to view Compute Node information

In the navigation bar, select Administrator-Calculation-Host Aggregation to enter the host aggregation list, and click Create Host Aggregation

In Host Aggregation, enter the host aggregation name HostAgr_web and the available partition name nova

Select Manage hosts in aggregation to add available host compute1 to complete host aggregation creation

Returns to the list of host aggregations showing the host aggregations you just created

It can be seen that the host aggregation has been successfully created.

Delete the hosts in the host aggregation. Click Delete in Manage Hosts in the Aggregation.

specification management

In Administrator-Calculation-Specification (Instance Type), go to the specification list and click Create Specification

In Create Instance Type Information, fill in as follows

Name: Flavor_web_test

vcpus:1

RAM(MB):128

Root Disk(GB): Root Disk Size, 1

Others remain default

Select Instance Type Access and add Project_web to indicate that the project can use the instance

Key pair and virtual machine group management

In "Project-Calculation-Key Pairs," go to the list of key pairs and click Create

Enter the key pair name "KeyPairWeb," and create

Save key pair locally

View key pair details

Virtual Machine Instance Operations

Select Project-Calculation-Instance in the navigation bar to enter the virtual machine instance list. Click Create Instance

On the details page, enter the instance name 'Instance_web01,' select nova and the number 1 of available partitions to issue virtual machine instances, and click Next

Go to the Source page, select No under Create New Volume, and check Img_web Mirror Add

Next go to Instance Type and add Flavor_web

Since no network and security groups have been created, skip and go directly to the key pair, select "KeyPairWeb

Click Create Instance

Returns the VM instance list, showing that the VM has been created and is running

Virtual machine instance opening and closing

In Project-Compute-Instance, go to the VM list, click Actions list, and select Close Instance

Same, can open instance

Hard restart, soft restart, suspend, lock, etc. of virtual machine instance can be completed through this interface

cli Operations Hypervisor, Host Aggregation and Available Partition Management Hypervisor Management

openstack hypervisor is a Hypervisor related command

View Virtual Machine List

openstack hypervisor list --long

View host list

Create host aggregation "HostAgr_cli"

openstack aggregate create --zone nova HostAggr_cli

Add host compute1

openstack aggregate add host HostAggr_cli compute1

specification management

Create the specification Flavor_cli and configure it as follows

vcpus:1

RAM:128M

Root Disk: Root Disk Size 1GB

This specification is visible only for Project_cli

Others Keep Default

openstack flavor create --vcpus 1 --ram 128 --disk 1 --private --project Project_cli Flavor_cli

View specs Details of Flavor_cli

openstack flavor show Flavor_cli

Flavor_cli is not public at this time. It needs to be public. It can be used by all projects. It needs to be deleted and recreated.

openstack flavor delete Flavor_cli

Re-create Flavor_cli and confirm that the specification is now public

openstack flavor create --vcpus 1 --ram 128 --disk 1 Flavor_cli

Key pairs and virtual machine management

Create Key Pair KeyPairCli

openstack keypair create KeyPairCli

Create virtual machine instance "Instance_cli_01" configured as follows

Available partition nova

Mirror image: Img_cli

Specification: Flavor_cli

Key pair: KeyPairCli

openstack server create --availability-zone nova --image Img_cli --flavor Flavor_cli --key-name KeyPairCli Instance_cli_01

Check the VM instance Instance_cli_01 status, Active means VM instance creation succeeded

openstack server list

virtual machine shutdown

openstack server stop Instance_cli_01

Check virtual machine status

openstack server show Instance_cli_01 | grep status

Start the virtual machine

openstack server start Instance_cli_01
