While testing my FPU patches on AMD's ZEN platform I noticed that the XSAVES feature flag was never used in the guest while it was present in the host. Patch #1 seemed to work but I holded on to it because I could explain why the guest did report ´fxsave_leak' while the host did not. It turns out that I need #2 _and_ tell qemu not to mask this information away. Sebastian
