...new features like AVX-512, MPX, etc. Refer to http://download-software.intel.com/sites/default/files/319433-015.pdf This patch adds support for these new instruction set extensions without enabling this support for guest use, yet. It also adjusts XCR0 validation, at once fixing the definition of XSTATE_ALL (which is not supposed to include bit 63).

The first patch really isn''t as much of a follow-up than what triggered the security issues to be noticed in the first place. 1: x86: preserve FPU selectors for 32-bit guest code 2: x86: fix XCR0 handling 3: x86/xsave: adjust state management 4: x86/fxsave: bring in line with recent xsave adjustments The first two I would see as candidates for 4.3 (as well as subsequent backporting,

v1 was here: https://www.redhat.com/archives/libguestfs/2016-March/thread.html#00157 Not running the 'hwclock' command reduces boot times considerably. However I'm not sure if it is safe. See the question I posted on qemu-devel: http://thread.gmane.org/gmane.comp.emulators.qemu/402194 At the moment, about 50% of the time is consumed by SeaBIOS. Of this, about ⅓rd is SGABIOS
