[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] 4.1 feature request: block device throttling/scheduling
Hello, This has already been added to the request list on the wiki, but I wanted to send a quick post here as well if there were any questions or comments. I have problems from time to time with guest VMs using up a lot more of my storage network than I would like. More than just priority scheduling, I would like to be able to tune how many read/write operations per second a VM can perform. Right now, without this ability on my storage network, I can end up having a VM that should be lower priority using up a lot of storage IOPS and starving everything else on the storage network. In an ideal world I could specify that vmX can perform Y writes per second and Z reads per second (since sometimes reads can be less expensive than writes) Please let me know if you have any questions. Adding something like this in would be *greatly* appreciated. Thanks, Thomas _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
