hello,
HUAWEI's FusionCompute prior to V100R006C10 uses the XEN architecture and uses para-virtualization technology. FusionCompute 6.3 and later versions use the KVM architecture and use hardware-assisted virtualization.
In my understanding, when installing Windows, in our virtualized environment, there is no need to turn on or off any switches separately. It should be possible to install the OS directly.
