I think I managed to track down the problem!
Replacing the kernel & initrd lines in the config file with:
bootloader = '/usr/bin/pygrub'
The domains seem to function without issue now.
I still seem to have problems starting hvm DomUs with Windows as the
guest OS. My guess is that something seems to be wrong with
pv-grub_x86_64.gz and possible hvmloader?
Has anyone managed to overcome, confirm or suggest a workaround for this?

kernel-2.6.38-1.xendom0.fc15.x86_64 & Xen 4.1.0
by Steven Haigh
Hi all,
I've rebuilt my xen server to Fedora 15 Beta which has Xen 4.1.0.
I've copied the config files from a working Fedora 14 & Xen 4.0.1 xen
server, however it seems that the guests refuse to start.
My config file is as follows:
memory = 512
name = "zeus.vm"
vcpus = 2
disk = [ 'phy:/dev/RAID1/zeus.vm,xvda,w',
'phy:/dev/RAID5/fileshare,xvdb,w' ]
on_poweroff = 'destroy'
on_reboot = 'restart'
on_crash = 'restart'
vif = [ "mac=02:16:36:35:35:09,bridge=br203,script=vif-bridge" ]
kernel="/usr/lib/xen/boot/pv-grub-x86_64.gz"
extra="(hd0)/boot/grub/grub.conf"
The only real message I can find says something about the kernel not
being a valid bzImage?
Is Fedora 15 + kernel-2.6.38-1.xendom0.fc15.x86_64.rpm a known working
configuration? Has the config changed between 4.0.1 and 4.1.0?

/sys/class/net/xenbr5/bridge: No such file or directory
by Jon R.
I followed Pasi's setup at
http://wiki.xensource.com/xenwiki/RHEL6Xen4Tutorial to configure and a
SL6 box. This all worked great and I have a working system. When I look
at my bridge with 'brctl show' I am seeing this as the output:

I am bonding my interface eth0 and eth1 and assinging the bridge to the
bond, here are my ifcfg scripts:

I read through this post,
http://permalink.gmane.org/gmane.comp.emulators.xen.devel/98821, and it
never did give an answer to what may be causing this. Is this something
that can be ignored?
Thanks for any help,

OProfile and Xen
by W. Michael Petullo
Is anyone using OProfile with Xen? I am especially interested in the
passive profiling of Xen DomU domains.
I've attached a Xen patch against the Fedora oprofile package to a
report in Bugzilla, #693596. But, even with this patch I am getting
mixed results.
