This is Ubuntu 14.04 GA (14.04.0), using the ISO/DVD install (kernel 3.13.0-24).

> client uname : root at ilp1fc85apA4:~# uname -a Linux
ilp1fc85apA4.tuc.stglabs.ibm.com 3.13.0-24-generic #46-Ubuntu SMP Thu

This version is way old (2014/04) for a bug reported on 2015/1, in
Ubuntu's fast pace.

Do the guest has any* other updates applied? (i.e., apt-get update && apt-get upgrade)
It seems there are no kernel upgrades as well?(i.e., apt-get update && apt-get dist-upgrade)

Any reason for not testing 14.04.1 or 14.04.2? (you can bump to it w/
dist-upgrade)

Also keep in mind that you need at *least* 14.04.1 in order to be able to do PCI passthrough with PowerKVM.

The attached patch should fix this issue.  Mauricio, please tell me what you think.

Gabriel,

Looks good to me.
Good discussion yesterday while traveling.

Let's hear on dm-devel.

Thanks!

Patch is applied to Christophe's tree. <https://www.redhat.com/archives/dm-devel/2015-October/msg00021.html>.

Now, let's get it downstream into Ubuntu.

== Comment: #34 - Gabriel Krisman Bertazi <gbertazi at br.ibm.com> - 2015-10-06 08:55:40 ==
Christophe Varoqui applied this patch to his multipath-tools tree <https://www.redhat.com/archives/dm-devel/2015-October/msg00022.html>.  

We would like it to be backported to Ubuntu to close this bug.
