I have a strange problem on one machine where eth0 gets killed when I add a virtual interface. It's got something to do with the NIC ordering or with the xen network script having a problem with multiple NICs and virtual interfaces. I could need some help/comments on this.
Some history: I added a NIC (chip identifies as Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet) to a Dell R200 server. CentOS 5.3 with Xen 3.3.1 (gitco repo).

This is a known issue with all Poweredge Servers. It will give you an explanation and workaround for it.
I don't think there is anything unique to Dells about this. The kernel essentially randomizes device naming on everything. Dell just took the trouble to document it.

From what I understand this was only with dell hardware that this was
happening and they submitted a patch to red hat. Also it is the only hardware I have encountered with the problem also. There could be others.
What's more is Kai says he's running 5.3 but the fix should be in that kernel. What I do wonder is if when the centos kernel was built, was it included? Maybe the CentOS Kernel builder could let us know?
2.6.19-rc3 and higher are supposed to have the fix?
It is however a strange thing when you encounter it. I pulled my hair for a long time.
Last thing is he has this problem on a R200 and from memory those were not a problem. Could be this is something new? He could check for a BIOS Revision if there is one.
