Beau, have you solved your performance problem already? Would you share what is the MTU you have set on the underlying network, and in your VMs? On Dec 13, 2017 17:41, "Dominik Holler" wrote: On Tue, 12 Dec 2017 23:12:12 +0200 Yaniv Kaul wrote: > On

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. On Mon, 11 Dec 2017 11:21:58 -0700 Beau Sapach wrote: > Yes, we've done some testing. With an oVirt VM running on a host > using

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
