Hi Christopher,

If you need some extended capabilities, the mainline kernel's Xen  
support won't be much help. That includes pci passthrough support  
(don't know when this'll ever be part of vanilla), but as long as you  
find the necessary patches, any kernel should work. I've found Xen  
patches for kernel 2.6.25 in the debian linux-image source package  
for example (though I haven't tried them yet, because it's a whole  
lot of work to extract the ones that are necessary) and for my IPCop  
Experimental DomU I'm using the Xen and IO delay patches from  
Ubuntu's linux-image-2.6.24-18-xen source package (this one still has  
some issues with pci_dma_xen-32.c and random crashes, but works in  
general) and I'm guessing there will be some patches for 2.6.26 in  
one distribution or another soon too. You'll need a bit of knowledge  
about how to extract the necessary stuff from those, about patching  
and building the kernel and probably about fixing some stuff by hand  
too (the Ubuntu 2.6.24 patches have issues with building a DomU-only  
kernel for example). You could always extract a precompiled kernel  
from a binary package though, but that might lead to problems with  
the system later (if some patch is missing for example).
Cheers,


Paul.
