No
I saw a patch to have it behave like this, but I can't find it right now.

Assuming that we use a 3 copy approach across the hypervisors, does Gluster
favour the local copy on the hypervisor if the data is on
distributed/replicated ?
It would be good to avoid the network hop when the data is on the local
disk.

You should indeed to use the same server running as a storage brick as a
KVM host to maximize hardware and power usage. Only thing I am not sure
is if you can limit the amount of host memory Gluster can eat so most of
it
gets reserved for the Virtual Machines.

Why don't you have KVM running on the Gluster bricks as well?
Good point. While abtracting we decided to seperate KVM & Gluster but I
can't remember why.
We'll think about that again.
We have a 4 node cluster (each with 4x 300GB 15k SAS drives in
RAID10), 10 gigabit SFP+ Ethernet (with redundant switching). Each
node participates in a distribute+replicate Gluster namespace and runs
KVM. We found this to be the most efficient (and fastest) way to run the
cluster.
This works well for us, although (due to Gluster using fuse) it isn't
as fast as we would like. Currently waiting for the KVM driver that
has been discussed a few times recently, that should make a huge
difference to the performance for us.
Ok! Thanks.
