So that I am understanding you correctly, the xen-4.1 doesn't use the
user-level block backend by default, it is just there to use until it is
added into the kernel.org kernel, correct? And from what you wrote, are
we looking at 2.6.40 for xen to be fully included into kernel.org? Very
good news if so!
I can use your repo and install your pre-built kernel on SL6 and build
xen-4.1 from xen.org from source and should end up with a stable xen
box? Sounds too easy. ;)
I had tried to use your repo on a FC14 box but something about my
hardware Fedora didn't like and would lock the box up randomly and I
couldn't track down the issue easily so I just left it behind because I
am not willing to dedicate the time right now to finding the cause. But
when I was trying to install using your repo I never could download the
'firmware' package, is that even needed if I use your repo?
Thanks Michael for all the effort you put into making this a simple
process, sure beats the old days of building the beast before there were
