how do you plan to use block storage for vm hosting?
With vm hosting you could create an additional qcow2 disk and access that
natively with qemu, isn't it?

It should way faster than using iscsi to access the block device on top of
gluster

I think that top priorities for gluster would be:

- small files performance so that gluster could replace NFS on almost every
workload (i know, writing 3 times like in gluster would be always slower
than writing once like in nfs, but the replica is not the only issue that
gluster has on small files. Ever a "ls -la" is slow)

- some way to add bricks in a number less than the replica count. I don't
know how but ceph does it even without EC thus there's a way to accomplish

In full replica 3 cluster,  adding a brick means adding at least 3 severs
with 1 brick each

DRBD9 does something similiar by adding one server at once and rebalance
the cluster

- native snmp monitoring (with smuxpeer or similiar, traps and so on).
Having a good monitoring system is mandatory in every production
environment . This could be really a plus for gluster. Triggering traps on
events is cool!
