Unable to configure the nfs-kernel-server (1:1.2.8-9ubuntu12.1) on Xenial KVM

[Po-Hsu Lin]

This issue was spotted with a KVM node running Xenial KVM kernel, it works well with generic / lowlatency kernel and B/C/D KVM kernels. (I guess maybe this is because of some missing configs?)

It was not spotted before as we don't install the nfs-kernel-server for SRU testing until commit https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/?id=db7879b27034eb2a1713256b654a4a127491a872

This is blocking the ubuntu_zfs_fstest as well.
