First time reporter, so apologies early on if I've gotten anything wrong here.

While trying to resize a RBD backed volume in our 4.5.1 installation (using the 
{{resizeVolume}} api call), the job fails with the error above. A [pull 
request|https://github.com/apache/cloudstack/pull/281] was merged in this space 
but it seems incomplete - you can see that {{getResizeScriptType}} in the 
source branch [returns 
null|https://github.com/remibergsma/cloudstack/blob/a26bbc2ce2f99e706895f9c0bbc6bdb5a522c37f/plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtComputingResource.java#L1824],
 but currently in master the above exception [is 
thrown|https://github.com/apache/cloudstack/blob/792c27c9bd97bc703ceb28fa8db24db7d0d46012/plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/resource/LibvirtComputingResource.java#L1428]

You can see a management server log snippet 
[here|https://gist.githubusercontent.com/DazWorrall/3bfcb153dea8b137f38b/raw/1f41096b247221e26b5407ae777f5fe278614d54/management-server.log],
 compete with traces.

This was discussed on the [mailing 
list|http://mail-archives.us.apache.org/mod_mbox/cloudstack-dev/201505.mbox/%3ccamvtbpou4tkan2kzknzpl0scu3y032ghu3av2qzgtsfas3t...@mail.gmail.com%3E]
 but I cant see if anything came of it. I can confirm the findings there though 
- going underneath Cloudstack and dealing with libvirt directly works fine, I 
can live resize root and data volumes without issue.
