2.install driver on guest
3.

Actual results:
install failed warning as "not compatible with your hardware" , details refer to the attachment 1 [details]

Expected results:

Additional info:

1 Tried with win10-32 and win2012R2, hit the same issue above
2 All the driver meet the same issue, eg. serial, rng, balloon, netkvm etc.
2 Boot without command "disable-legacy=on,disable-modern=off", there is no warning
3 it is a bit strange that it list all the model when install only one driver.

It only report a warning, it can install successfully for serial,rng and balloon.
But the netkvm, blk and scsi, pvpanic cannot install w/ virtio1.0 device.
