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.
