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.

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,
