Why might the standard Fedora7 kernel work OK, but the Fedora7 xen kernel not work? Is it perhaps because of missing drivers in the xen kernel?
I can not say something specific regarding your hardware but I had a similar problem with Fedora 6 and a Dell Dimension system about 7 months ago. The problem was that the broadcom network chipset has some internal limitations regarding the memory address size it can address. At that time, Xen did not have a workaround for this so the linux driver (b44) won't work with a Xen kernel while working well with an standard kernel.
So in essence, it may be a combination of hardware limitations and/or Xen that your hardware does not work with Xen. Maybe incomplete Linux drivers. Searching bugzilla helped me at that time :-)
