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
You may adjust the way the NFS server works by specifying NFS server attributes using the https://24hwritemyessay.com command. installation became a breeze. Configuration turned into trivial, specially in comparison to the Hummingbird and Microsoft NFS servers.

Meh! Is spam really the only response I'm going to get on this? On 3/10/19 1:45 PM, John Florian wrote:

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.

You are welcome to share.

Thank you, this exactly what I wanted to know (and suspected). -- John Florian
