Re: [ovirt-users] 10Gb Networking with OVN
Yes, we've done some testing. With an oVirt VM running on a host using
10Gb ethernet copying data to a physical machine also using 10Gb ethernet
we don't see network utilization exceed 800Mbits or so. A bit of research
online yields some experimentation done by others who used SR-IOV to
achieve 10Gb from a VM.
I'm not sure where the bottleneck is, possibly in the VirtIO driver.

Is there an indication that the VMs will not take advantage of 10Gb?
