oVIRT 3.5 / Virtual Machine / 10GB possible?

We are running oVIRT 3.5, until one of vendors supports us moving to 4.0. Our RHV hosts have 20GB aggregated NICs on the box, however our VM's I notice only have 1GB NICs available. I do see that the Virtual machine is using the "virtio-net-pci" device, is there a way to get this Virtual Machine to have a 10GB NIC? When i run 'atop' on the RHV host I notice that it claims the virtual NIC is hitting 100% utilization at times. What methods do I have available to increase the 1GB NIC to something higher hopefully to 10GB ? -- Devin Acosta Red Hat Certified Architect, LinuxStack 602-354-1220 || devin@linuxguru.co

Disregard that number. It's a virtual NIC, and so is the 1g number. Y.

Yaniv, So are you telling me that the virtual machine will get 10Gbit speeds even though it only reports 1Gbit? On Tue, Mar 14, 2017 at 10:43 AM, Yaniv Kaul <ykaul@redhat.com> wrote:

Yes, theoretically. The historical reason is that when it was developed, there was a need to display some link speed (ethtool, Windows device manager) and back then 1g seemed like high speed. Getting really 10g is a challenge, but I have seen 7-8g on a bright day. Y.

It is up to the driver used on the VM and what the qemu process does with it. by default, neither libvirt or vdsm will mess with it. You will find that qemu also has no restrictions on bandwidth, but only the driver used. Using the virtio driver, ethtool will return no speed data, because there is none. Settings for eth0: Link detected: yes That is all.

Windows WHQL (driver signing) process mandated some speed (as it is displayed to the user), so I guess that's why it was added. Y.
