Do you have any experience with kernel 2.6 and Citrix XenServer? Myself and a many more people on the Citrix XenServer forum have problems with Ubuntu 10.04 (2.6.32-23-server #37-Ubuntu SMP) and there is no idea to have a right host (dom0) configuration. If you have an idea please contact me. Thanks for this useful post. Do you have any experience with kernel 2.6 and Citrix XenServer?
