Hello Yang,
To add to this, a list of mandatory packages would be helpful as well
(like if I need some additional virtio- packages). Thank you,

Hello Yang,
allow_unsafe_interupts actually means the interrupt remapping on
Intel IOMMU which is a security feature. Without it, a malicious VM
can attack the host, see below document for more details:

Should I take that to mean that "allow_unsafe_interrupts" is actually
a security feature??? Is this the discussed "interrupt remapping" in
the whitepaper? I am interpreting that paper as saying that this
interrupt remapping does *not* use the supplied DMAR table. Is that
correct?
Also, you can try to upgrade your BIOS to fix it.
I'll take a look but I think I have the latest (which means, from
~2011 probably) BIOS version.
Could I also ask you outright what entire set of boot options you
would pass when booting into a kvm system with IOMMU enabled? I would
love some "default" set of boot options to compare to, as opposed to
random ones from assorted forums.
Thank you for the prompt reply!
