I'm even wondering who has what speed of export VM or live storage migration? I just don't understand how to increase it. ZFS replication goes 300-400MB/s with the same load. With regards, Roman Cherkalin

This is very cryptic: care to expand a little? oVirt supports live migration--of VMs, meaning the (smaller) RAM contents--and tries to avoid (larger) storage migration. The speed for VM migration has the network as an upper bound, not sure how intelligently unused (ballooned?) RAM is excluded or if there is some type of compression/sparsity optimization going on.
