最近幫公司購買新的PC, 也是這張MB "ASUS Prime X299-Deluxe II"遇到同樣的問題, Hyper-V背後需要的HV Host Service因偵測不到VT導致Service無法啟動, 但VirtualBox運作都正常

搞了好幾天終於try成功, 主要原因應該是新版bios的bug
我的操作順序如下
1. Check bios setting, VT and VMX皆已開啟
2. OS Enable Hyper-V
=> 測試啟動HV Host Service發生Error
3. Disable "DeviceGuard"
=> 測試仍然無法啟動HV Host Service
("gpedit.msc", setting "Computer Configuration\Administrative Templates\System\Device Guard\Turn On Virtualization Based Security” to “Disabled”.)
4. bios reset to default setting
5. flash bios to 0210 ver (最舊的版本)
=> 測試仍然無法啟動HV Host Service
6. bcdedit /set hypervisorlaunchtype auto
=> 測試成功啟動HV Host Service
