For example with bionic, i40evf module is in linux-modules-extra-4.15*-generic. However, cloudimg doesn't have linux-modules-extra seeded:

$ curl -s http://cloud-images.ubuntu.com/releases/bionic/release/ubuntu-18.04-server-cloudimg-amd64.manifest | grep linux-
linux-base 4.5ubuntu1
linux-headers-4.15.0-65 4.15.0-65.74
linux-headers-4.15.0-65-generic 4.15.0-65.74
linux-headers-generic 4.15.0.65.67
linux-headers-virtual 4.15.0.65.67
linux-image-4.15.0-65-generic 4.15.0-65.74
linux-image-virtual 4.15.0.65.67
linux-modules-4.15.0-65-generic 4.15.0-65.74
linux-virtual 4.15.0.65.67

We don't need the whole linux-modules-extra because the size is not small, but we need some VF drivers in cloud guest image embedded for SR-IOV enabled cloud including OpenStack. Otherwise, the guest is unusable with no network device.
