Thank you Adam to point out my misinterpretation. Now I understand that Sean asked about how am I sure that all those zeroes generated in one host are really going to the other. > The sender can send as many packets as its CPU can possibly send, even if 99.9% of those packets are getting dropped by the receiver; the sender still thinks it "successfully" send a bazillion bytes per second even though it's a meaningless number. Good point, as this: > FWIW, you're almost certainly going to be CPU-bound. I can't get more than ~200Mbps on an emulated em(4) interface under ProxmoxVE (KVM 1.7.1) between two VMs running on the same host. Granted, the CPUs are slowish (2.2GHz Xeon L5520). I get better throughput using vio(4) but then I have to reboot the VMs once every 2 or 3 days to prevent them from locking up hard. > What version of ProxmoxVE? I am considering this as a counterpart to XenServer, but I have some kind of faith in hypervisors in Xen and VMWare style, but in this project I can not afford VMWare prices. Thank you again, Adam!
