virsh domblkinfo 64 vda

  virsh blkdeviotune shows values in raw bytes, which is  difficult to read. it show add a parameter like -h to show the values in megabytes or gigabytes.

I've just pushed patch upstream:

commit 4b9af8625a642339526b47eff718fab12c4b7cea

    virsh-domain-monitor: add human readable output for 'domblkinfo'.
    
    https://bugzilla.redhat.com/show_bug.cgi?id=1330940
    
    The virsh command 'domblkinfo' returns the capacity, allocation and phisycal
    size of the devices attached in a domain. Usually, this sizes are very big
    and hard to understand and calculate. This commits introduce a human readable
    support to check the size of each field easilly.
    
    For example, the command before:
    
    virsh # domblkinfo my_domain hda
    Capacity:       21474836480
    Allocation:     14875545600
    Physical:       21474836480
    
    and after this patch:
    
    virsh # domblkinfo my_domain hda --human
    Capacity:       20.000G
    Allocation:     13.900G
    Physical:       20.000G
