May 7, 20197 yr I have been conversing in this other thread (below) but felt guilty about stealing it, especially since it is marked solved, so starting a new one. Stubs and such like don't seem to be working. The config I'm using is as below. kernel /bzimage append xen-pciback.hide=(0b:00.0)(0b:00;1),vfio_iommu_type1.allow_unsafe_interrupts=1 isolcpus=12-15,28-31 initrd=/bzroot I have tried unsafe interrupts added to the append command also, which didn't change anything either. Any ideas? obi-wan-diagnostics-20190507-0155.zip

Be carful with the options you set in the syslinux config. They have to be separated by a space and not a comma.
May 7, 20197 yr Author OK, I'll give it a go. One of the guides (I think the space invader one) specifically stated to use commas, then some follow up responses stated they saw no difference with or without a comma. Will give it a go when I put my NIC card back in shortly.
May 7, 20197 yr Author I replaced the card. So assuming the card reseating didn't achieve it (and I have no reason to assume it did), this seems to have worked. Thanks for your help. I might do some testing with commas again later just to be absolutely certain.

Thank you for this tip! Mine looks like this now: append vfio_iommu_type1.allow_unsafe_interrupts=1 pcie_acs_override=downstream,multifunction iommu=pt vfio-pci.ids=8086:105e initrd=/bzroot Edited May 17, 20197 yr by guruleenyc
