From 23da6073369ef6a99d1789de967e57359d1fe3b0 Mon Sep 17 00:00:00 2001 From: Stefan Dirsch Date: Tue, 26 Apr 2016 16:26:49 +0200 Subject: Disable "acceleration" under qemu Disable "acceleration" under qemu, since taking the hypercall trap is really quite expensive and you're better off doing noaccel.
