I see there is no support built for RDMA from the QEMU build log for
16.10 @ https://launchpadlibrarian.net/285349205/buildlog_ubuntu-
yakkety-ppc64el.qemu_1%3A2.6.1+dfsg-0ubuntu3_BUILDING.txt.gz
RDMA support no
We need QEMU to be built with RDMA support

Including Brian King here as I am not sure it will be possible to enable this
feature in Ubuntu 17.04.
In order to build QEMU with RDMA support, we would need to have RDMA
devel packages installed on the build machine. My understanding is that,
for Ubuntu in general, IBM is going with MOFED drivers. However, in the
environment Canonical is building QEMU, there is no MOFED, as MOFED is
not a package supported by Canonical. If they build QEMU with RDMA
support in their environment, it will probably not work with MOFED RDMA
support. Could you please advise, Brian?

Per discussion with Brian, moving this to 18.04.
