File 0020-tools-kvm_stat-Add-Python-3-support-to-kvm_stat.patch of Package kvm_stat.12295
From 27ffcf036bda1ca51997197ec0c8977293cfb4c9 Mon Sep 17 00:00:00 2001 From: Jeremy Cline <jeremy@jcline.org> Date: Wed, 4 Oct 2017 03:08:11 +0000 Subject: [PATCH 20/43] tools/kvm_stat: Add Python 3 support to kvm_stat MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make kvm_stat support Python 3 by changing the use of "print" to a function rather than a statement, switching from "iteritems" and "iterkeys" (removed in Python 3) to "items" and "keys" respectively, and decoding bytes to strings when dealing with text. With this change, kvm_stat is usable with Python 2.6 and greater.
