Using rados-java as a new Maven dependency for KVM

Hi,

In the rbd-snap-clone [0] branch I'm working on the new RBD features 
like snapshotting, cloning and deploying System VMs on RBD.

To do this correctly I wrote Java bindings for librbd and librados (part 
of the Ceph project).

These bindings [1] are just like libvirt-java just JNA bindings for 
these libraries. Since these bindings aren't in Maven central I created 
a Maven repository on Ceph.com [2] and I added it to the pom.xml of the 
KVM plugin for the Agent.

Can we accept this as a dependency? It's just a Maven dependency which 
doesn't include any binary code into the Git repo.

The bindings are currently GPLv2 licensed since that's what Ceph uses, 
but does this conflict with the Apache project? I want to make sure it 
will be included in the OSS builds of CloudStack, so I can change the 
license if required.

I'm not a lawyer, so I'm not so sure about this.

Thoughts?

Wido

I wrote all the code. So I just released version 0.1.1 which is licensed 
ASLv2.

I just went for LGPLv2 because I needed some license. These are just 
bindings, so I don't care that much.

Any objections against using this?

Since it looks like you wrote all of this particular piece of
software, can you dual license? LGPLv2 and ASLv2? (or BSD or MIT for
that matter)

This is going to be problematic with that license.  See:
http://www.apache.org/legal/resolved.html

We put things like this in the non-oss build OR specify that they need
to be installed prior to our software being installed / built (calling
them system dependencies).

It would be *much* easier for it to be re-licensed with a license that
the ASF has approved as compatible with ASLv2.

I have to correct myself here. The license is LGPLv2 for both Ceph and 
the Java bindings.

RE: Using rados-java as a new Maven dependency for KVM

Posted by Edison Su <Ed...@citrix.com>.
Just curious: Do you plan or already implement librbd api call with progress callback? The storage operation usually takes a long time, without progress bar, it's very difficult to know what's going on at the storage side.
