Xen might not be compatible with the card, it is not listed by intel as compatible [URL] nor is it on the HCL from citrix [URL]   You are going to have to manually compile it for the OS [URL] [URL]    
Hi all, I have a problem with Dell R710. Originally it came with Broadcom network cards, but we have to add Intel. We've replaced it with Intel I350T2BLK, but I can't use it - no traffic. In the OpenManage we can see: [IMAGE] "eth6" NIC details are odd as well: [IMAGE] There is Citrix XenServer 5.5 OS. Please advise what is wrong with new network card and how to fix it?  Thanks,
