Hi All,
    I met "KVM internal error. Suberror: 3"  when I reboot the  guest(Windows 10 with intel HD graphics pass through).

  If I removed the configuration of hyperv enlightenments of cpu, it will be ok.

  If I updated the guest from win10_32 with version 1703 (15063.0) enterprise to win10_32 with version 1803,it will be ok too.

  Can someone tell me why or give me some tips about how to debug such problems ?

  Any pointers would be greatly appreciated.

Best regards,
