Hi all, is there a way to limit the throughput (or the number of operations per seconds) of a block device?
I ask because I've a couple of misconfigured VMs that are performing a lot of disk activity (swapping I'd bet but I haven't access to their OS). Since their storage is on a NFS share they are slowing down other VMs on the same share.
Thank you. Davide.
Hi, there is <blkiotune> [1] that controls the throughput for the whole domain and <iotune> [2] that controls it for each block device. Martin [1] http://libvirt.org/formatdomain.html#elementsBlockTuning [2] http://libvirt.org/formatdomain.html#elementsDisks
