The machines are running Ubuntu 18.04 with kernel 4.15.0-55. The dpdk-devbind.py tool outputs "Cannot bind to driver vfio-pci" and "Cannot open /sys/bus/pci/drivers//unbind". The dmesg output contains "vfio-pci: probe of [PCI Address] failed with error -22" whenever I try to bind it. Both machines have "intel_iommu=on iommu=pt" in their kernel parameters.

Vt-d is enabled now for both machines, but the same error -22 is still occurring in dmesg. `/sys/kernel/iommu_groups/` is empty. Perhaps the kernel parameters are not being set properly?

Try to modprobe vfio-pci and see whether it shows under /sys/bus/pci/drivers/. If this is the case, then you may want to add vfio-pci to /etc/modules so that it gets loaded automatically on boot.

What did you enable in the bios, it mostly doesn't come with name 'Vt-d' so may be hard to find it?
