In my oVirt deployment at home, I'm trying to minimize the amount of physical HW and its 24/7 power draw. As such I have the NFS server for my domain virtualized. This is not used for oVirt's SD, but rather the NFS server's back-end storage comes from oVirt's SD. To maximize the performance of my NFS server, do I still need to use bonded NICs to increase bandwidth like I would a physical server or does the VirtIO-SCSI stuff magically make this unnecessary?
This depends on the scenario. Bonding two VirtIO vNICs connected to the same network would be not increase the throughput, since a single vNIC has by default no artificial bandwidth limit. But bonding two SR-IOV VF on two different NICs might be increase the performance.
In my head I can argue it both ways,
You are welcome to share.
but have never seen it stated one way or the other, oddly.
