Synergy : The Technology behind XenClient / Synchronizer for XenClient

Citrix announce one fact : 72% of devices will be laptop.

Citrix XenClient is a type 1 hypervisor (bare metal) and can run in stand alone mode without the back end Citrix XenClient Synchronizer. This is build on the 64 bit open source technology used with XenServer and you can run multiple virtual desktops simultaneously. Different VMs are completely secure isolation from each other and are hardware independent VM. A named call Service VM Architecture has been develop for extensibility.

XenClient provide a good end user interaction and advanced security for your devices and you data. With centralized security policies you can for example allow one user to run a VM for 4 days in a offline mode and if the suer doesn’t connect on internet the VM will be shutdown until the user is able to connect and authenticate to request more time.

The XenClient SDK should be available in 2011

The Citrix Receiver for Xenclient is the first Service VM for XenClient. Using Citrix Receiver for XenClient provide a very simple user interface to access, create and configure VM locally. You can very easily switch between local VMs.

Synchronizer for XenClient is the backend to manage XenClient and manages centralized delivery of VMs. It also provide a full time backup & rapid recovery with a smart backup delta data. You can remote kill VMs and manage local policy controls with Citrix Synchronizer for XenClient.

A bit of architecture : XenClient is based on a very thin piece of code taken and shared with XenServer. This is a linux control Domain and you will use paravirtualized drivers as well as being able to allow direct access to hardware for a specific VM. The XenClient user interface is Receiver for XenClient.

Flexible Virtualization Architecture, as mention above, disks, networks devices, USB and graphics devices are virtualized and ensure VM portability. You have also a selective passthrough, 3D Graphic Direct, Intel AMR Direct : Mix and match : You can give Direct access to GPU to a specific VM, same for storage and network separately (?) to confirm.

Synchronizer for XenClient Architecture : Synchronizer will be provide as a XenServer image and will be up and running within 10 minutes (Merchandising Server like cli wizard). The admin interface is web based (https) and authentication can remain local or being linked with an Active Directory. VM delivery and administration are using a single network port, https (443)

Scalability : 10 users is ok, need to test more to know more…

Future : XenDeskop integration is plan

Tips : Control shift +T  to have a shell window poping up and then you can check local VMs (.VHD) in there >> /storage/disks/
