From 303d4e865b74402b49f52e975c396c952f063e58 Mon Sep 17 00:00:00 2001 From: Anthony PERARD Date: Tue, 21 Sep 2010 20:05:31 +0100 Subject: Introduce -machine command option. This option gives the ability to switch one "accelerator" like kvm, xen or the default one tcg. We can specify more than one accelerator by separate them by a colon. QEMU will try each one and use the first whose works. So, ./qemu -machine accel=xen:kvm:tcg which would try Xen support first, then KVM and finally TCG if none of the other works. By default, QEMU will use TCG. But we can specify another default in the global configuration file.
