[Qemu-devel] [PATCH] -machine vmport=off: Allow disabling of VMWare ioport emulation |
Date: |
Mon, 19 May 2014 18:00:26 +0100 |
From: "Dr. David Alan Gilbert" <address@hidden>
VMWare apparently doesn't like running under QEMU due to our
incomplete emulation of it's special IO Port. This adds a
-machine suboption to allow it to be turned off.
