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.
