Accidentally set domain memory to 30Gb, system only has 32Gb of RAM
-
And I believe this is causing the system to not boot. I get a kernel panic with an error about not being able to enable IOMMU.
What's the easiest way to fix this? Or am I looking at a complete re-install/upgrade type fix?

Edit grub before it boots and reduce the number
Then it will boot, and re-enter the correct amount -

Quick follow up questions, if I change it in Grub, is that change permanent, or do I still need to change it via the CLI or in Xencenter?

IIRC, it will be permanent until there's another Grub update that will regenerate the menu. So it's not really permanent and it's better to use XO/CLI/whatever supported client to modify the value.
