In my OpenStack installation (Icehouse and use nova legacy networking)
the VMs are talking to each other over a 1Gbps network link.
My issue is that although file transfers between physical (hypervisor)
nodes can saturate that link transfers between VMs reach very lower
speeds e.g. 30MB/s (approx. 240Mbps).
My tests are performed by scp'ing a large image file (approx. 4GB)
between the nodes and between the VMs.
I have updated my images to use e1000 nic driver but the results remain
What are any other limiting factors?
Does it has to do with the disk driver I am using? Does it play
significant role the filesystem of the hypervisor node?
Any ideas on how to approach the saturation of the 1Gbps link?
