            Bug ID: 194923
           Summary: kvm-intel.nested=1 does not enable nested KVM
           Product: Virtualization
           Version: unspecified
    Kernel Version: 4.8.17
          Hardware: Intel
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: kvm
          Assignee: virtualization_kvm@xxxxxxxxxxxxxxxxxxxx
          Reporter: R030t1@xxxxxxxxx
        Regression: No

Kernel is booted with kvm-intel.nested=1 in arguments. `cat
/sys/module/kvm_intel/parameters/nested` is "N".

These steps work for kernel 3.18.9. I apologize if the severity is too high,
but this is a serious regression and prevents usage of previously available
functionality.

Bug 64801 and 76141 may be related.
