Don't forget to run a ping with a size of 8500 and "do not fragment" flag. This will really prove that you are no longer using the small MTU anywhere on the path.

The NIC is virtual, it's not going to show a link speed. This doesn't have much to do with the old version of oVirt, I run the newest version and ethtool simply outputs . that a link is detected with no other details. The VMs will run at whatever speed is configured on the host backend.

The first thing that comes to my mind is to check the network's MTU.By default it is 1500, and I suppose you can go with MTU 9000Also , check if OS is using MTU 9000 Best Regards,Strahil Nikolov В вторник, 9 юли 2019 г., 9:58:47 ч.
