[vfio-users] Help Patching Qemu for Vendor

[Spam House]

Thanks for the fast responses!

I must be trying to add it the wrong way.

sudo EDITOR=nano virsh edit win10

add:
    <hyperv>
      <relaxed state='on'/>
      <vapic state='on'/>
      <spinlocks state='on' retries='8191'/>
      <vendor id='none'/>
    </hyperv>

Saving results in:
error: unsupported configuration: unsupported HyperV Enlightenment feature:
vendor

Any suggestions? Thanks again!
