pure master, ie, "-cpu host..." This may still be a limitation of the host CPU. quite convinced about that :) , after trying to solve/understand the mess about x2APIC on these processors for the last days (sidenote, I have to start my host system (see above) with kernel parameter nox2apic, because the up-to-date BIOS still forbids it. x2APIC is emulated by qemu) Could you try "jailhouse hardware check" with this patch on the host? > sure, reflects exactly what I found by fiddling in vmx.c: with default start-qemu.sh -> "XSAVES MISSING" ... "Check FAILED!" with "-xsaves" added to qemu's -cpu param -> "XSAVES missing (optional)" ... "Check passed!" (and it seems usable) [image: jh_hw_chk_wPatch-xsaves.png] [image: jh_hw_chk_wPatch.png] <about:invalid#zClosurez> -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
