** Description changed: There are two essential kernel modules that are missing from some linux kernel packages under Ubuntu Server 18.04 LTS: nfsv4.ko and aes-x86_64.ko (matter-of-fact any crypto module) I found them both missing in linux-kvm and nfsv4.ko missing in linux- generic - both are present in linux-generic-hwe-18.04. The use cases for these are not far-fetched: In an Ubuntu KVM guest, I often need virtual disks that I can encrypt via LUKS in order to protect them (somewhat). Obviously, this is not possible without the crypto modules, which are not present in the KVM- specialised kernel package 'linux-kvm'. On the other hand, when I want to mount NFS storage, I cannot use NFSv4, which is the preferred way of doing it when you need firewalling. Why this fails is not at all obvious, since the use-level "mount.nfs4" is present, but only gives cryptic messages, not showing that a kernel module is missing. And even with the default kernel (linux-generic), which has some more modules, NFSv4 client support is missing. - Do I really have to use linux-generic-hwe-18.04 for that? It seems a bit - much. + Do I really have to use linux-generic-hwe-18.04 for that?
