thanks for your interest. Could you elaborate what your thoughts related 
to CentOS 7 and the CentOS virtualization SIG are? I am not sure I 
exactly understand what you are proposing and it is also not quite clear 
to me whether there is some overlap with other SIGs (such as the Cloud SIG).

I guess the key question I have is whether you are suggesting / 
considering to use the output of the virtualization SIG as upstream for 
OpenNode and would want to contribute to the SIG.

Best Regards
