From 745cb07a0d0090283383a35656bd0af36c446377 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Thu, 4 Dec 2014 09:12:27 +0000 Subject: [PATCH] v2v: Disable autoreboot when converting Windows guests. This allows users to see stop errors, so we can get an accurate report when things go wrong.
