How to Enable the vSwitch

[root@xenserver-demo2 network-scripts]# xe-switch-network-backend openvswitch

Cleaning up old ifcfg files

Remove... ifcfg-eth0

Remove... ifcfg-eth0.5

Remove... ifcfg-eth1




Remove... ifcfg-xapi1




Remove... ifcfg-xenbr0

Remove... ifcfg-xenbr1

Enabling openvswitch daemon

Configure system for openvswitch networking

You *MUST* now reboot your system

• Enhanced scalability and testing

• GPU Passthrough

• Local Storage caching to offload SAN

XenDesktop Optimizations

The Xen Team……

• 512 GB RAM support

• Multi-CPU Dom0 increases

responsiveness and scale

• Enhanced focus on pool scalability

and XD/XS best practices in 5,000+

desktop blocks

XenDesktop Optimizations – Enhanced Scalability

The Xen Team……

• Experimental GPU Passthrough - Ability to assign

power user VMs 1:1 to Graphics Cards

• Works with nVIDIA FX3800, 4800,

5800 GPUs

XenDesktop Optimizations – Graphics Enhancements

The Xen Team……

• Local host caching of

XenDesktop images

• Reduces IOPS on shared

storage, lowering storage

TCO

• Technology preview in

XD5, fully supported early

2011

XenDesktop Optimizations – IntelliCache

The Xen Team……

1. Master Image created through XenDesktop MCS

2. VM is configured to use Master Image

3. VM using Master Image is started

4. XenServer creates read cache object on local storage

5. Reads in VM being done from local cache

6. Additional Reads done from SAN when required

7. Writes will happen in VHD child per VM

8. Additional VMs will use same read cache

9. Local “write” cache is deleted when VM is shutdown/restarted
