[ovirt-users] VM bandwidth limitations

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?  In my head I can argue it both ways, but have never seen it stated one way or the other, oddly. -- John Florian
