Libvirt + Qemu/KVM IOMMU Pass-through machine no longer boots

This VM used to work fine until recently. Possibly some update to qemu or libvirt but I'm not sure what. It says the VM is booted, but the graphics card doesn't output anything and it never boots into windows as it should auto login and connect to synergy.

qemu log file:

EDIT: If anyone else is having a similar issue I fixed* it by patching qemu-git with https://lists.gnu.org/archive/html/qemu … 03629.html and the setting the cpu type to core2duo instead of Haswell-noTSX

*fixed in the sense it works even though the cpu type should be Haswell-noTSX but that doesn't boot.
