Hi Jason Villalta, In LibvirtVmDef.java, there is DiskDef class , get the cache value from the Global config, while constructing the xml in the override method the class toString() specify the cache value, currently it is using "none".
NOTE: whenever there is change in GC value, MS should restart for the value to take effect.
