Description ybendito 2021-02-07 11:04:33 UTC

Description of problem: When the VIOPROT protocol installed, is does not bind to netkvm adapter (that's correct). But it is possible to enable binding of the protocol to netkvm adapter and this causes immediate BSOD.


Version-Release number of selected component (if applicable):
0.1.193

How reproducible:
100%


Steps to Reproduce:
VM with virtio-net (no need to have VF). Install VIOPROT protocol. Go to Control panel - Network and Sharing center - Change adapter settings - VirtIO adapter - Properties - enabled check box VirtIO NetKVM protocol driver - OK.

Actual results:
BSOD

Expected results:
At least this should not do anything bad.
