Hello, Does anyone know of any work in progress or any tricks to limit a guest's i/o requests to a specific throttled rate? I have guests that mount their filesystems via virtio, which are images served on an NFS server. Some of these guests will flood the server with requests and can then choke out the i/o requests of neighboring guests. I'd rather be able to specify that certain guests can only get so many read or write iops. i/o bandwidth rates would be nice, but iops tend to be the killer since an nfs server only has so many.
I've seen something recently on a block i/o throttling via cgroups, but from what I've been able to grok... this support is being built only with local devices in mind? I'm afraid that wouldn't work for my NFS server setup and image files? Is there something that can be done from with virtio? Or another trick?
