[linux-azure] Missing user mode io driver - uio_pci_generic

[Joseph Salisbury]

After creating a Lv2 VM (OS - ubuntu 18.04) it was found that uio_pci_generic is missing. It is needed to attach SPDK to nvme disk.

The kernel build config file that Canonical provides in Ubuntu 18.04 images shows CONFIG_UIO_PCI_GENERIC=m, indicating that the module was built. However, the module is not included in the image.

Is there a reason why the uio_pci_generic module is not included in the Azure Marketplace image? If not, can we get it added back in?
