have a feeling you might have had some NFS related issues with your
write performance. If that is the case, then NFS tuning will be
required to get what you are looking for.
I only have the one server. I could do a oVirt All-In-One install and
use local storage on it. You may be right about the NFS side of things;
it did occur to me to. All the other tests I did (ESXi, "vanilla" KVM)
use true local storage.
If it works fine with the AIO/local storage install, then at least that
gives me something to look at (NFS storage)
I may be able to get to this tomorrow, but it may not be until Thu or
Fri that I can report on results, so please be patient :-)
