From b4e022916c98628425ff1bcf92b419dd61fa78d1 Mon Sep 17 00:00:00 2001 From: "Richard W.M. Jones" Date: Tue, 19 Jul 2011 19:55:24 +0100 Subject: [PATCH] build: Fix virtio-serial test for qemu 0.15. Now qemu 0.15 won't even start up unless the -machine accel=... option is specified. Essentially this is a regression in qemu.
