Title:
unable to enable iommu on HPE Proliant Gen9 server
Status in linux package in Ubuntu:
Incomplete
Bug description:
I'm using MAAS to enable the following kernel flags on install/boot:
iommu=pt intel_iommu=on
in order to be able to passthrough SR-IOV VF functions to KVM guess;
however when these options are enabled, the servers fail to install
(see attached screenshot).
The install eventually fails - it looks like the writes back to one of
the disks starts to fail for some reason.
Servers are targeted with Xenial and the release 4.4 kernel (no HWE).
