Subject RE: Drop OVM in 4.0?
Date Thu, 18 Oct 2012 20:54:03 GMT
Yesterday, I read a blog talking about open source project(,
in the " Project direction and priorities " section, which makes sense to me:

"An open project and its community are the sum of individual people doing what they care about.
It's flat-out wrong to think that any healthy open project is a pool of developers who can
be assigned priorities that "make sense" globally. There's no product manager. The community
priorities are simply the union of all community-member priorities."

Take OVM as an example, apparently, it's not in the Citrix's CloudPlatform team's highest
priority. If other people want this feature, the idea situation is to pick it up by yourself.
I think Marcus set a great example about how to work with community under this situation.
We, the community, are open to bug fix, feature enhancement etc. 
I like to hear the voice from OVM user or developer. How many users are caring about OVM?
Is there any other developer, other than people coming from Citrix, can or want fix OVM issues?
Is it acceptable to move OVM to 4.0.x release?
