13.3. Viewing virtual machine storage information by using the command line

Procedure

1. To view the available storage pools on the host, run the virsh pool-list command with options for the required granularity of the list. For example, the following options display all available information about all storage pools on your host:

   # virsh pool-list --all --details
   
    Name                State    Autostart  Persistent    Capacity  Allocation   Available
    default             running  yes        yes          48.97 GiB   23.93 GiB   25.03 GiB
    Downloads           running  yes        yes         175.62 GiB   62.02 GiB  113.60 GiB
    RHEL-Storage-Pool   running  yes        yes         214.62 GiB   93.02 GiB  168.60 GiB

   • For additional options available for viewing storage pool information, use the virsh pool-list --help command.

2. To list the storage volumes in a specified storage pool, use the virsh vol-list command.

   # virsh vol-list --pool <RHEL-Storage-Pool> --details
    Name                Path                                               Type   Capacity  Allocation
   ---------------------------------------------------------------------------------------------
   
     RHEL_Volume.qcow2   /home/VirtualMachines/RHEL8_Volume.qcow2  file  60.00 GiB   13.93 GiB

3. To view all block devices attached to a virtual machine, use the virsh domblklist command.

   # *virsh domblklist --details <vm-name>
   
    Type   Device   Target   Source
   -----------------------------------------------------------------------------
    file   disk     hda      /home/VirtualMachines/vm-name.qcow2
    file   cdrom    hdb      -
    file   disk     vdc      /home/VirtualMachines/test-disk2.qcow2
