Cool!

This needs integration tests with real vdsm, or at least a server using vdsm

yajsonrpc code. I'm worried about incompatibilities between the go stomp

library and our own stomp implementation, not used by any other code.

When it works, we can convert vdsm-client to go :-)

Great! make it official under ovirt imo . This will be totally useful later on with openshift integration. Im almost convinced that once ovirt will run in parallel to openshift or as part of openshift, we'll need to call vdsm api commands via modules that with high chance will be written in go. Give specific example won't be meaningful much because we still designing all this vm+containers architecture and flows.

Thanks

Awesome Piotr!  Thanks for the great work.

Adam asked for the client for his storage related changes. I am not
sure about specific use case.

I am looking at implementing a vdsm flexvol driver for kubernetes.  This would allow kubernetes pods to access vdsm volumes using the native PV and PVC mechanisms.

By no means example is not perfect and you are correct. I will fix.
