[ Upstream commit 933b5f9f98da29af646b51b36a0753692908ef64 ]

Instead of printing an error message, kvm_stat script fails when we
restrict statistics to a guest by its name and there are multiple guests
with such name:

# kvm_stat -g my_vm
Traceback (most recent call last):

' to specify the desired pid'.format(" ".join(pids)))
TypeError: sequence item 0: expected str instance, int found

To avoid this, it's needed to convert pids int values to strings before
pass them to join().
