It is more a NFS issue, if you have a file in NFS that two users in
two different host are accessing (one at least write to it) you will
need to enforce the "sync" option.
Even if you flush all the data and close the file the NFS client can still
have cached data that it didn't sync to the server.

For NFS you need to use the sync mount option to force the NFS client to
sync to
server on writes.
Isn't opening with O_DIRECT enough? (for linux nfs client at least)

Hi!
I have yet another problem with migration. Or NFS.
There is one NFS server and 2 test POWER8 machines. There is a shared NFS
folder on the server, mounted to both test hosts. There is an qcow2 image
(abc.qcow2) in that shared folder.
We start a guest with this abc.qcow2 on the test machine #
