[vfio-users] Virt-manager setup issues - CPU "host-passthrough" - can't boot media using edk2 EFI - no bridge available

OS: Arch Linux x86_64
Mobo: ASUS Sabertooth X99
CPU: i7-5930K
GPU: Gigabyte Nvidia GTX 970

I've successfully installed qemu, libvirt, edk2.git-ovmf-x64 and vfio-linux.  I have successfully dedicated one gpu to vfio and the other to the nvidia driver.  Each of my gpus are listed in different groups, so I don't need the ACS over ride patch.  As such, I'm using the standard kernel.

I'm following the following guide in an attempt to setup the initial VM but I'm running into various problems.

  1. If I manually enter "host-pass-through" in Processor>CPUs>Configuration>Model:, my host will lock up when I click "Begin Installation".  My only option is to hard reset the host.  I've been using Haswell-noTSX instead.  Will this be okay?  What would cause "host-passthrough" to freeze my host like that?

  2. When booting to the EFI shell, I'm unable to load the linked virtio drivers or the Windows 10 install iso, even though I've selected them as IDE CDROM 1 & 2.  When I select CDROM 1 in the boot options of the EFI shell, it says to press any key to boot from cd rom, but when I do nothing happens and it goes back to the EFI shell.  Is this likely a problem with my isos or is it possible that I'm doing something wrong?

  3. I don't have the Bridge option available as a network source.  Is this something I can create through virt-manager or do I need to look elsewhere.  If you know of a link, it would be very helpful - I'm don't know enough about how this works to google the right keywords.
Any help that you can provide is greatly appreciated.
