This makes it harder to read and convert. It would be easier if it's logged in MB and Mbps.


Version-Release number of selected component (if applicable):

OpenShift Virtualization   4.11.2

How reproducible:

100%

Steps to Reproduce:

Do a live migration and monitor the source virt launcher pod for migration info.

Actual results:

Migration info are logged in bytes and is not easily readable.

Expected results:

Log the data in MB and Mbps.
