Oracle VM server and virtual machine Network too slow
I have facing couple of problems with network in Oracle VM.
I have gigabit network card and gigabit network( I can verify that its gigabit because when i connect same network cable to Windows, it shows 1000 Mbps). No matter what parameter I set for Network card, it just takes 100 Mbps speed.
Second, I am facing issues with network between two Virtual machine (Domu). When I try to copy files from one machine to another, I get only 6 - 7 Mbps speed. For copying 2 GB file between two machine takes more than 5 mins While If i copy on same machine it takes less than 40 secs.
I tried ethtool - K eth0 tx off on both virtual machine, however I am still getting same speed.
I was thinking that when two virtual machines are running in same domain (dom0) , Intreconnect speed is same of xenbr0 or xenbr1.
I even created paravirtualized machine but network is still too slow.
Following is output from Oracle Vm server. I have just one cable connected to eth1.
