X58 Virtualization w/ Linux

Hello,

I was instructed to send an email to the KVM-devel group about this. I
made a post on reddit about some issues I've had virtualizating an X58
environment. The details are here:

https://www.reddit.com/r/homelab/comments/4njtoi/x58_virtualization_w_linux_xpost_rlinux4noobs/

I'm asking around to see if anyone has a straightforward solution, or
any advice on how to approach this problem. Also (please read the reddit
post first):
- can I just pass "GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on
vfio_iommu_type1.allow_unsafe_interrupts=1" safely?
- is there a way to fix the DMAR table for my BIOS (see post)? How
might I dump it and fix it?

I'm running barebones Arch and KVM/QEMU. My progress is outlined in that
reddit post and discussion. At the moment, I'm after "safe" passthrough
of a PCIe NIC and video card to separate VMs. "Safe" may mean totally
secure (secure passthrough), or just stable enough that I don't have to
debug problems every kernel update *whichever is possible*. Thank you
in advance for any help.

Sincerely,
--
