Hi, the latest “feature” update of Windows 10 seems to break the IGD passthrough on my VM. I get the serial console as usual, but when Windows starts to use the Intel driver I get vertical dotted stripes, instead of 20 minutes circling update completion dots. The VM continues to run and remains active, judging from IO activity. My rom file has been fixed with rom-fixer. Found nothing too obvious in the logs.
Any thoughts? Kernel version is 4.12.5. Thanks, Manuel Note: replaced some values by placeholders indicated by '-' pre- and suffix. libvirt XML: <domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <name>win10</name>
