Using the `virsh pool-start` command (with examples)
The virsh pool-start command is used to start a previously configured but inactive virtual machine storage pool. This command is part of the virsh tool, which is used for managing virtual machines and their resources.
In this article, we will explore different use cases of the virsh pool-start command and provide code examples for each scenario.
Starting a storage pool with build option
To start a storage pool and create the underlying storage system if it doesn’t exist, we can use the --build option with the virsh pool-start command. This option allows us to automatically create the storage system when starting the pool.
Here is an example of how to start a storage pool and create the underlying storage system:
virsh pool-start --pool name|uuid --build
--pool name|uuid: This argument specifies the name or UUID of the storage pool we want to start.--build: This option indicates that the underlying storage system should be created if it doesn’t already exist.
Motivation for using this example
By using the --build option, we can ensure that the storage system for the virtual machine pool is automatically created when starting the pool. This eliminates the need for manual configuration and setup of the storage system.
Example output
Pool mypool started
In this example output, the storage pool named “mypool” has been successfully started, and the underlying storage system has been created if it didn’t already exist.
Conclusion
The virsh pool-start command is a useful tool for starting virtual machine storage pools. By providing different options, such as --build, we can automate the creation of the underlying storage system when starting the pool. This simplifies the management of virtual machines and their resources.
