Also I tested Windows Server 2008 R2 - also can't load vioscsi driver. Also I tested with qemu-kvm-ev-2.6.0-28.el7_3.3.1.x86_64 - also can't load vioscsi driver. Also I tested two different CentOS 7.3 servers, with different CPUs: Intel(R) Xeon(R) CPU E5-1650 v2 @ 3.50GHz Intel(R) Atom(TM) CPU C2750 @ 2.40GHz - also can't load vioscsi driver in Windows Server 2012 R2 setup. Why I can't load vioscsi driver in Windows Virtual Machine?
