> When using LibvirtDomainXMLParser  parser xml from Domain.
> The attribute diskCacheMode not always have value , and will be empty string
>  String diskCacheMode = getAttrValue("driver", "cache", disk);
> when the code go to here valueOf
> } else if (type.equalsIgnoreCase("block")) {
>                         def.defBlockBasedDisk(diskDev, diskLabel,
>                             DiskDef.diskBus.valueOf(bus.toUpperCase()));
>                         def.setCacheMode(DiskDef.diskCacheMode.valueOf(diskCacheMode));
> }
> There will be cause IllegalArgumentException at 
> at java.lang.Enum.valueOf(Enum.java:196)
> I suggest we may check if diskCacheMode is empty string , such as
> if (diskCacheMode == null || diskCacheMode.isEmpty()) {
> 	def.setCacheMode(DiskDef.diskCacheMode.NONE);
> } else {					
> def.setCacheMode(DiskDef.diskCacheMode.valueOf(diskCacheMode));
> }
