Bug Description

The test provided for libhugetlbfs along with ubuntu_beta release fail.

Steps to recreate:

1. apt-get install libhugetlb
2. cd /usr/lib/libhugetlbs
3. ./

Unable to find available page sizes, are you sure hugetlbfs
is mounted and there are available huge pages?

We see the above message.

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.

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 for documentation how to enable and use -proposed. Thank you!
