So recently I deployed 3 XenServer 6 hosts with local storage only. Our need was to virtualize approx 6 very old Centos QA servers running on ancient hardware. Since I did not have any dedicated network/san storage at my disposal I stuck 6, 146 SAS drives in each server and carved them up into a 410GB raid 10 array. However the XenServer install did not detect this secondary logical disk, so I had to figure out how to manualy create a storage repository using this new drive.

I digress.

XenServer Switch Ports Configuration Best Practices
Finally I have found it! Citrix's XenServer switch configuration best practices document. While everyone in the world has blog posts and documentation regarding how to set up and configure bridged networks in Xen, they hardly ever go into the physical switch configuration required. This is the document that you will need to pass along to your friendly Network Administrator, as they will more than likely not be familar with networking for Xen as its much different from networking for Vmware ESX.
