Subject Re: Opportunity to contribute in Apache CloudStack
Date Fri, 15 Jul 2016 13:27:00 GMT
Jainesh,

As Syed mentioned, today Xen support in CloudStack is limited to XenServer
(or more precisely XAPI, but today XAPI really is only used with
XenServer). In 2014, I put forth a proposal to rectify that [1]. That
proposal contained two steps, first we needed to clean up the use of Xen
when XenServer (XAPI) was implied, and second was to implement a libvirt
interface for Xen in CloudStack. The cleanup was completed with ACS 4.5
[2], but the libvirt work required some upstream changes in multiple
projects. Those upstream changes were actually completed for OpenStack
Liberty last year [3][4], with the result being Xen became a "Group B"
hypervisor over there. I *feel* we're now in good shape to begin the second
part of the effort and have Xen + libvirt become fully supported with
CloudStack.  Syed and I spoke about this at the CloudStack Collaboration
Summit in Montreal last month.

I'll respond next week on the security proposal, in part as I'm gathering
the API references.
