QoS doesn’t do much good. I need to be able to set an upper limit of reads/writes ops. QoS won't stop a VM from bringing down an entire storage.

Could this be what you're looking for? Surely this is also available in XCP. http://docs.vmd.citrix.com/XenServer/5.6.0fp1/1.0/en_gb/reference.html#disk_qos On 16 February 2011 19:40, Tomoiaga Cristian <[email protected]> wrote: Well, the XenCenter issue is partially solved now anyway. A way bigger issue is being able to throttle iops/vdi. Seems nobody wants to answer if it’s possible (I am sure it is) and if there are any plans to implement something. VMWare already has this and I am amazed why this is treated as not being important since almost everyone has problems when one VM creates too many/sepcific IOPS. Regards, Tomoiaga
