I forgot to reenable VT-d support in the BIOS after updating, solved the original issue…
(XEN) Command line: loglvl=all guest_loglvl=all xsave=1 iommu=1 iommu_inclusive_mapping=1 ucode=scan
(XEN) Intel VT-d iommu 0 supported page sizes: 4kB.
I then ran in to another error

libxl: error: libxl_domain.c:886:domain_destroy_cb: Domain 1:Destruction of domain failed
And from xl dmesg
(XEN) XEN_DOMCTL_assign_device: assign 0000:04:00.3 to dom1 failed (-12)
If I didn’t attempt to passthrough the device the domu started up..
Going back through the config example I had not enabled the viridian setting as it was commented out on the example, and did not exist in my original settings. This was apparently a new feature that you need to enable for passthrough to work, even though I could not find any info on that being a requirement.
The things you miss when you leave a system alone for 2+ years because it was working perfectly fine.. LOL

Subject: [Xen-users] Unable to add passthrough devices to my domu?
I’m attempting to start my domu where I am passing through a network card for exclusive use. But I get an error that it cannot be assigned no IOMMU, but I do have it enabled in the grub config.
Ideas, recommendations?
