virsh-domblklist:tldr:e21c0
The command "virsh domblklist --domain ${vm_name}" is used to list the block devices attached to a specific virtual machine (VM) using the virsh tool.
Here is an explanation of each part of the command:
-
"virsh": It is a command-line interface tool commonly used to manage and control virtualization hosts and VMs. It is specifically designed for managing virtual machines using the libvirt API.
-
"domblklist": It is a specific subcommand of the virsh tool used to obtain a list of block devices attached to a domain (VM) or display information about block devices attached to a domain.
-
"--domain ${vm_name}": It is an argument passed to the "domblklist" subcommand to specify the target domain (VM). The "${vm_name}" variable is used to represent the name of the virtual machine, allowing you to pass the name as a value when executing the command.
In summary, the command is basically used to get a list of block devices (such as virtual disks) associated with a particular virtual machine.
