From 2d4e4c01b1a9f5c4f9d066cfdd3fd66542faa8bb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Alex=20Benn=C3=A9e?= Date: Tue, 22 Jan 2019 11:49:57 +0000 Subject: [PATCH] scripts/qemu.py: allow arches use KVM for their 32bit cousins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A lot of architectures can run their 32 bit cousins on KVM so the kvm_available function needs to be a little less restricting when deciding if KVM is available.
