[11u] RFR: 8250598: Hyper-V is detected in spite of running on host OS

[Yasumasa Suenaga]

Hi all,

Please approve backport of JDK-8250598:

    JBS: https://bugs.openjdk.java.net/browse/JDK-8250598
    Original fix: https://hg.openjdk.java.net/jdk/jdk/rev/80c95309a924
    webrev for 11u: http://cr.openjdk.java.net/~ysuenaga/JDK-8250598/jdk11u/webrev.00/

The patch does not apply cleanly on 11u due to additional enhancements to x86 / x86_64 processors.
So I've prepared another webrev for 11u.


Thanks,

Yasumasa
