Comment 8 for bug 1835275

The only network kernel modules missing is the bond kernel module however the ephemeral environment is missing a few others

ib_iser - OpenSCSI, which is in the ephemeral image, wants to load this kernel module. This is causing systemctl is-system-running to show up as degraded. Since we were already discussing adding Infiniband drivers for IBM S390X I think we should add these
aes_x86_64 - This autoloads once I install the linux-modules-$(uname -r) package. This kernel can be used by the RAID driver to get faster performance. Since a deployed Ubuntu environment will have this I think we should add it as well
hid_generic, virtio_gpu - Both are accelerated drivers for using user input with KVM. Since most users are using the VM remote and few if any install a graphical environment I think we can continue to skip these.
