I would like to correct this. Arm guests are more equivalent to x86 PVH than HVM. For more details, see: https://wiki.xenproject.org/wiki/Understanding_the_Virtualization_Spectrum#PVH: This is also why we need a brand new solution for PCI passthrough rather than piggying back on what was done on HVM in QEMU :).
