I have the hard coded parameter changed and the system Proxy VM is running now but I am running into issues with the secondary storage vm. Troubleshooting that now. As for the cache setting, I think that still need to be setup as a configurable option without a rebuild. Once I get the cloud fully functional I will have some time to contribute to this issue. For now I just need to get this up and running.

For example some primary storage may need this set to one value such as cache=writeback such as with the case of ZFS, GlusterFS, CEPH. Then other storage may want a different setting such as cache=writethough or none which is the case with a local ext4 storage or NFS. Exactly. I brought this up about a week ago, see this thread: http://markmail.org/thread/qmrod55gfmhwzot4 It shouldn't be a global property, it should be defined per storage pool, or even better, per disk offering. Right now we are talking about the cache setting, but tomorrow it could be a different setting.
