From b65cc8dec07fec77dbda7bc5daf1defcb7c411d9 Mon Sep 17 00:00:00 2001 From: Alexandro Sanchez Bach Date: Wed, 14 Nov 2018 17:33:30 -0800 Subject: hax: Support for Linux hosts Intel HAXM supports now 32-bit and 64-bit Linux hosts. This patch includes the corresponding userland changes. Since the Darwin userland backend is POSIX-compliant, the hax-darwin.{c,h} files have been renamed to hax-posix.{c,h}. This prefix is consistent with the naming used in the rest of QEMU.
