Hi Tim,

Note that the referenced commit only makes it so that if you don't back a PowerKVM guest with hugepages, hugepages do not (falsely) appear to be supported. In such an environment the message referenced in this bug report will still be displayed as it should -- hugepages aren't supported in such a guest.

To run the libhugetlbfs test suite in a PowerKVM guest, you must back the guest with hugepages in the host and then allocate hugepages in the guest as appropriate.

Thanks,
Nish

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

All information about hugepages is still available. As per the patch provided in defect https://bugs.launchpad.net/tasty-taco/+bug/1295705, the hugepage data should not be available. However it doesn't seem to be the same.

This sceanrio as a result will be a FAIL.

Kindly do run through my patch application steps and  let me know if the right steps have been followed or should I be choosing a different repo altogether.
