        When I got hs_err log on Windows, I saw "HyperV virtualization detected" in it in spite of running on host OS.

        Hypervisor detector has been introduced in JDK-8219241, but it has some problems as below:

          - Hyper-V is detected on Windows in spite of running on host OS
          - Call CPUID with other than EAX = 40000000h (it is not described in the spec [1])
          - Does not check CPUID hypervisor present bit [1]
          - Does not support x86 (32bit) platform
