Is there a way to limit IOPS from a guest VM to external storage?

Guest vm is running Oracle Linux 7.2.  PCA is running 2.1.  Guest is a HVM-PV Linux instance.

I have a guest VM that is running custom code do DNA sequence comparison.  The developer has mapped a large file to memory in order to improve application performance.  This runs on dedicated hardware but when we run it on the PCA, it drives IOPS on the external storage to the point that all the VM's experience storage time-outs.  Windows host end up frozen while linux hosts are able to recover.

Is there a way to limit the number of IOPS the PCA infrastructure provides to a guest?

Howdy, Stranger!
