Subject [jira] [Created] (CLOUDSTACK-1301) VM I/O Throttling
Date Fri, 15 Feb 2013 15:31:12 GMT
Wei Zhou created CLOUDSTACK-1301:

             Summary: VM I/O Throttling
                 Key: CLOUDSTACK-1301
             Project: CloudStack
          Issue Type: New Feature
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.0.0
            Reporter: Wei Zhou

VM I/O Throttling, to set the maximum disk I/O rate of VMs.

Virtual machines are running on the same storage device (local storage or share strage). Because
of the rate limitation of device (such as iops), if one VM has large disk operation, it may
affect the disk performance of other VMs running on the same storage device.
 It is neccesary to set the maximum rate and limit the disk I/O of VMs.
