Re: [Xen-users] Xen Networking Issue with Scientific Linux 4

[Ivan Porro <pivan@xxxxxxxxxxxxx>]

Hi

I suggest you to start eliminating the kernel issues. The 2.4 kernel in 
SLC 3 is creating some problems to you.
If you manage to download packages from the domU or from the dom0 
loop-mounting your VM filesystem, you may find useful this link:
http://linux.web.cern.ch/linux/scientific3/docs/kernel26.shtml

hope this help solving part of your issues
