Re: [ovirt-users] 10Gb Networking with OVN
Thanks for the hint, we are going to check this.
You are welcome to share if you have any hints about a possible
bottleneck in you scenario.

Yes, we've done some testing. With an oVirt VM running on a

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.
