[Bug 1788336] Re: Failed to install nfs-kernel-server package on X/X-KVM

[Po-Hsu Lin]

For the Xenial generic kernel:

ubuntu at larry:~$ find /lib/modules -name 'nfsd.ko'
/lib/modules/4.4.0-139-generic/kernel/fs/nfsd/nfsd.ko
ubuntu at larry:~$ dpkg -S /lib/modules/4.4.0-139-generic/kernel/fs/nfsd/nfsd.ko
linux-image-4.4.0-139-generic: /lib/modules/4.4.0-139-generic/kernel/fs/nfsd/nfsd.ko

But for the linux-KVM kernel, it seems there is no such module there:
ubuntu at larry:~$ uname -a
Linux larry 4.4.0-1037-kvm #43-Ubuntu SMP Fri Oct 26 10:50:03 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
ubuntu at larry:~$ find /lib/modules -name 'nfsd.ko'
/lib/modules/4.4.0-139-generic/kernel/fs/nfsd/nfsd.ko


And I have checked the kernel config for Xenial/Bionic KVM kernel:
# CONFIG_NFSD is not set

So yeah, you're right, there is no such support for the KVM kernels
