Hello guys, I was wondering if anyone has successfully managed to set IO limits in ACS 4.2.0. I've done some testing and I can't make it work.
I've created two disk offerings, one with 20MB/s limit and another with 50MB/s. I've added both to a vm and dome simple dd tests. The limits are not working and I can successfully read and write faster than 200+MB/s. I've checked the kvm vm xml definition file and I can see the iotune parameters like these: Disk 1 with 20MB/s limit : <iotune> <read_bytes_sec>20480000</read_bytes_sec> <write_bytes_sec>20480000</write_bytes_sec> <read_iops_sec>500</read_iops_sec> <write_iops_sec>500</write_iops_sec> </iotune> Disk 2 with 50MB/s limit: <iotune> <read_bytes_sec>51200000</read_bytes_sec> <write_bytes_sec>51200000</write_bytes_sec> <read_iops_sec>1000</read_iops_sec> <write_iops_sec>1000</write_iops_sec> </iotune> I am using Ubuntu 12.04 servers with ACS 4.2.0 + KVM (libvirt 1.0.2 and qemu 1.5.0) + RBD primary storage. Could you please point me in the right direction how to setup the IO limits? thanks Andrei
