[Fedora-xen] Xen Dom0 and Fedora 14

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 2.6.35.4. Am I missing something here? Is building a 2.6.35.4-based 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 detect_dev_info pos = self.find_cap_offset(PCI_CAP_ID_EXP) File "/usr/lib/python2.7/site-packages/xen/util/pci.py", line 933, in find_cap_offset 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)) to: try: id = ord(os.read(fd, 1)) except: pos = 0 break; 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. -- Mike :wq
