<div dir="ltr">Hi Doug, I guess this is part of QEMU 2.5 by now. On the command line you can use it as followes: -cpu host,hv_time,hv_vendor_id=KeenlyKVM I don´t know if this is also in libvirt already. But I can't tell if you have any advantage of this right away. I tried this along with hv_time on my existing Windows 7 VM, and it wasn't able to start because of hv_time. So maybe you need to do a fresh install at least - but I'm not sure. PS: the patch is located here: <a href="https://www.mail-archive.com/qemu-devel@nongnu.org/msg328958.html">https://www.mail-archive.com/qemu-devel@nongnu.org/msg328958.html</a> Alex </div><div class="gmail_extra"> <div class="gmail_quote">On Mon, Jan 11, 2016 at 6:31 PM, Doug Applegate <<a href="mailto:doug.applegate@gmail.com" target="_blank">doug.applegate@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello, I recall someone mentioning that Alex had a patch to QEMU that avoids the need for disabling hypervisor enlightenments if you were using nVidia graphic cards. Is this in upstream QEMU, if it is has it been released? Or do I need to patch QEMU first? Where exactly is this patch?
