windows 10 and QXL dod driver
QEMU KVM Host
- RHEL 7.6
- Libvirtd 4.5.0
- virt-manager 1.5.0
- virt-viewer 5.0-11.el7
- Windows 10 with spice client tools
- QXL dod graphics driver version 18

Using RDP to windows 10 VM with still the QXL divers used.
This is the XML for the host:
And some spice debug output when working in the Excel document.
Please let me know if you need more info
