<p>Why on earth are you using wrapper script? If you use shellscript
to start qemu then add these flags there. If you are using libvirt
- libvirt also supports these features. This mess is looking for a
trouble and i believe you found it.<br>

<div dir="ltr">I'm trying to use a Windows 10 Enterprise guest but
keep getting error 43 with my Nvidia 750Ti card. I have set the
kvm hidden state flag and well as overriden the vendor_id flag
via a wrapper script as suggested by other users on this mailing
list:
<div><br>

<div>
<div>
<div>#!/bin/sh</div>
<div>exec /usr/bin/qemu-system-x86_64 \</div>
<div> `echo "\$@" | sed
's|hv_relaxed|hv_relaxed,hv_vendor_id=KeenlyKVM|g'`</div>

<div>Similarly I have tried removing everything from the
hyperv tag section as well as ensuring there isn't any
hypervclock timer tag. Unfortunately no combination of
hyperv settings seems to bypass Code 43. This isn't a
hardware problem because passthrough works fine with an
Arch Linux guest. The full xml is located here <a
moz-do-not-send="true"
href="http://pastebin.com/3zta7eW1">http://pastebin.com/3zta7eW1</a>.
I cannot place the vendor_id flag in the xml because it
is validated in the Ubuntu package, but as mentioned
above I am interdicting the command line args. This made
me suspect that the Ubuntu packages were too outdated,
so could that be the reason?</div>
<div><br>
</div>
<div>In Ubuntu 16.04 the package versions are:</div>
<div>libvirt: 1.3.1</div>
<div>qemu-kvm: 2.5<br>
virt-manager: 1.3.2<br>
<br>
Currently running kernel: 4.4.0-37</div>
