Comment 4 for bug 1797715

Odd, that seems as if the guest request for an IP never reach the host at all.

I'll take a look at the following error:
  virNetDevSendEthtoolIoctl:3071 : ethtool ioctl error: No such device

Could you:
- check if dnsmasq processes are running as I outlined?
- have any chance to try a Linux guest as well so we know if this is win-guest specific?
- you have a virtio setup, did you configure virtio drivers for windows on your own - if so how exactly?
- Could you try to switch to a non virtio card for a test to check if it is windows virtio support?
- if it affects only windows, could you describe the version of the guest OS that is affected?
