Disk i/o information like throughput,activity or latency, or at least some disk related data, by which the throughput, activity or latency can be calculated. Is there any virsh command or some method in python-libvirt library, that would help me in finding these value?

You can install the top like utility virt-top, which is used for virtualization stats. You can get network, memory, cpu and block device statisticts of domains.

To install virt-top utility on Debian/Ubutnu use:

$ sudo apt-get install virt-top

For Redhat/Centos use:

$ sudo yum install virt-top

Start using virt-top with:

$ virt-top

And you'll see something like this:

If you'd like to save the info from virt-top to a file for analyzing you can save it to a csv file like this:

$ virt-top --csv output.csv

Read the manual page man virt-top for more examples.
