hyper-v disables vt-x for other hypervisors RRS feed

  • คำถาม

  • Hello,

    I just installed windows 8 pro on my working computer.
    I work a lot with virtual machines for special os setups. Recently I used Virtualbox for those machines.
    But with windows 8 pro VBox says there is not VT-X available ... (mainboard and processor support vt-x and it is enabled)
    Well it was available before I switched to windows 8 pro.

    I search the net and found a hint that hyper-v might be the cause. I had hyper-v installed because I am planning to migrate to hyper-v from vbox.

    I uninstalled hyper-v and vt-x was available again. Question now is why does hyper-v does disable vt-x for other hypervisors or even better how can i prevent this ?
