Sateesh As mentioned before I have a good number of vSphere environments using dvSwitches that I can't roll into CS just yet.
Whenever you are ready to test something or have a proof of concept code to try - I can assist. I've been meaning to ask - are you planning to build any controls that are available via VCenter for dvSwitches - or is it strictly support and enablement? Thank you -ilya -----Original Message----- From: Sateesh Chodapuneedi [mailto:sateesh.chodapune...@citrix.com] Sent: Monday, December 17, 2012 2:41 PM To: cloudstack-dev@incubator.apache.org Subject: [ASF41][DISCUSS] Adding support for VMware dvSwitch Hi, I am planning to work on enabling support for VMware native dvSwitch in CloudStack. Filed a jira ticket for it, see [1]. Integration of VMware dvSwitch with CloudStack enables orchestration of virtual networks in VMware environment over distributed virtual switch inside vCenter. Background ----------- VMware Distributed Switch is an aggregation of per-host virtual switches presented and controlled as a single distributed switch through vCenter Server at the Datacenter level. vDS abstracts configuration of individual virtual switches and enables centralized provisioning, administration, and monitoring. vDS is integral component of vCenter. Hence the native vDS support makes sense for wider and larger deployments of Cloudstack over vSphere. Each Standard vSwitch represents an independent point of configuration that needs to be managed and monitored. The management of virtual networks required by instances in the cloud is tedious when virtual networks have to span across large number of hosts. Using distributed vSwitch (vDS) simplifies the configuration and monitoring. Being standalone implementations, standard vSwitches do not provide any support for virtual machine mobility. So there needed a component to ensure that the network configurations on the source and the destination virtual switch are consistent and will allow the VM to operate without breaking connectivity or network policies. Particularly during migration of VM across hosts, the sync up among peers need to be taken care. However in case of distributed vSwitch during VMotion, the vCenter server, would update the vSwitch modules on the hosts in cluster accordingly. I'll share an FS for this in the next few days. Please do let me know your thoughts/concerns. [1] CLOUDSTACK-657 - "VMware vNetwork Distributed Virtual Switch support in CloudStack" Regards, Sateesh
