I am looking for a solution that will allow me to control I/O usage for my home Xen based cluster. Basically what I need is a way to limit or scale domUs (VMs) disk throughput. E.g. setup: - VM1 volume1 250MBps volume2 50MBps - VM2 volume1 100MBps
As far as I know I can use block devices like ceph RADOS or LVM, but what solution can you guys suggest for disk I/O control and scalability?
