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

It seems that our oVirt instance never exceeds 550Mbps aggregate traffic (rx /
tx) according to nvstat. I want to make sure that the negotiated speed,
handshaking, etc. are all what I expect them to be from the OS level.

oVirt Enginge Version: 3.5.0.1-1.el6 (yes....I know it's old)
VM is running Ubuntu 18.04 with ovirt agent installed.
I'm attempting to get NIC information by running 'ethtool -i ens3' I get the
following:
root@myserver:~# ethtool -i ens3
driver: virtio_net
version: 1.0.0
firmware-version:
expansion-rom-version:
bus-info: 0000:00:03.0
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no
root@myserver:~#
and when I run 'ethtool ens3' I get the following:
root@myserver:~# ethtool ens3
Settings for ens3:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: Unknown!
Duplex: Unknown! (255)
Port: Other
PHYAD: 0
Transceiver: internal
Auto-negotiation: off
Link detected: yes
This is not what I expected. Is there another tool I should be using to display
the information for ens3 on this server?
Best regards,
