--cpu_affinity 2,3,6-8
8 PCPUs: 2/3/6/7/9/10/11/12
--cpu_affinity 2,3,6-7,9,10-12
The specified pCPUs must be included in the guest VM's statically

After Windows 10, version 1607, the cross-signed drivers are forbiden
to load when secure boot is enabled.
Details please refer to
https://docs.microsoft.com/en-us/windows-hardware/drivers/install/kernel-mode-code-signing-policy--windows-vista-and-later-

So we found another windows virtio FE drivers from Oracle to resolve this issue
but have to change another subsystem vendor ID for the virtio BE services.
This patch introduces a new DM CMD line "--windows" to launch WaaG with Oracle virtio devices including
virtio-blk, virtio-net, virtio-input instead Redhat. It can make virtio-blk, virtio-net and virtio-input
devices work when WaaG enabling secure boot.
