Server and client are both kvm guests.  I'm running xfstests with a
bunch of known-to-fail tests excluded:

	cat >/etc/xfsqa.config <<EOF
	TEST_DIR=/mnt
	TEST_DEV=$server:/exports/xfs2
	NFS_MOUNT_OPTIONS="-overs=4.1"
	EOF
	./check -nfs -g auto -E ~/xfstests-skip

where xfs-tests-skip is:

Kernel is 26cbcc77df, from

	git://linux-nfs.org/~bfields/linux-topics.git for-4.0-incoming

(just upstream 6587457b4b3 plus your fix for layout_fail recursion).

I have another exported xfs filesystem on this server that's on a device
shared with the client, but this filesystem isn't.

Config has basically all the NFS stuff turned on (including NFSD_PNFS).

Gory details in an ugly pile of shell scripts at
git://linux-nfs.org/~bfields/testd.git.

What other problems?
