I have been investigating the use of Xen with a Fedora 14 (devel)-based
Dom0. Until now, I have always used Michael Young's Dom0 kernels.

The first thing I did was try to build the current Fedora 14 kernel with
Xen Dom0 support. I began porting Michael's RPM specification to the
Fedora 14 specification. What I found was that the Xen pvops work seems
to be targeting 2.6.32 and possibly 2.6.36. As a result, I was unable
to find a straightforward way to create a patch for Am I
missing something here? Is building a kernel difficult
in this way?

Next, I tried to use Michael's latest Fedora 12 kernel on Fedora
14. Of course, Fedora 14 uses some features that are not available
in this kernel. Most notably, I had to provide the kernel with the
"init=/sbin/upstart" option to avoid the use of systemd.

Once I booted the system, I found that xend would not start because it did
not find what it expected in /sys/bus/pci/devices/0000\:00\:03.2/config:

  File "/usr/lib/python2.7/site-packages/xen/util/pci.py", line 1050, in 
    pos = self.find_cap_offset(PCI_CAP_ID_EXP)
  File "/usr/lib/python2.7/site-packages/xen/util/pci.py", line 933, in 
    id = ord(os.read(fd, 1))
TypeError: ord() expected a character, but string of length 0 found

I "fixed" this by editing pci.py and changing:

id = ord(os.read(fd, 1))


    id = ord(os.read(fd, 1))
    pos = 0

Of course, this might not be a good fix, but it was quick and it allowed
me to continue and experiment. Does anyone know what is going on here?

At this point, I was able to boot a DomU image, although I need to do a
lot more testing. Has anyone else experimented with Fedora 14? What is
your experience? I am especially interested in hearing about Fedora 14
Dom0 kernels.
