Hi, I'm having trouble installing a fedora f20 guest on a centos5
host, I previously had a working f16 guest, so I guess I want to
know if this is possible or not.
virt-install seems to work ok as before, but then the reboot fails
with this error:
Error starting domain: POST operation failed: xend_post: error from
xen daemon: (xend.err "Error creating domain: Boot loader didn't
return any data!")
I've tried formatting /boot as ext2 and ext3 with the same result,
now I'm out of ideas. Here is my virt-install command:
virt-install --paravirt --name honk --ram 2048 --disk \
path=/dev/VolGroup02/LogVol12 --vnc --location \
http://dl.fedoraproject.org/pub/fedora/linux/releases/20/Fedora/x86_64/os/

F20 as a paravirt guest should work, but I think nowadays most people are
using fullvirt xen, so maybe paravirt isn't tested as much with new distros.
I'm just guessing though
Regardless, you'll probably have to dig in xen logs to or do some googling to
find more info: I don't have any idea. It's very unlikely to be a
virt-install/libvirt issue though

Sorry, I thought this email went to the upstream virt-manager list, hence I
was focusing on that :)
RHEL5 xen is an old frankenstein monster at this point as well, so could be a
xen issue that just hasn't been backported.
CCing fedora xen list as well, maybe they have ideas.

Thanks, I tried with --hvm instead of --paravirt, but this fails:
ERROR Host does not support virtualization type 'hvm

RHEL5 xen is an old frankenstein monster at this point as well, so could be a
xen issue that just hasn't been backported.

I would need to see more logs to be sure, but I would guess pygrub is
missing at least one update and this one
http://xenbits.xenproject.org/gitweb/?p=xen.git;a=commit;h=d513814db6af2b...
is a possibility. You could test if it is pygrub by running directly - in
your case try
/usr/bin/pygrub /dev/VolGroup02/LogVol12
as root - it should give you a choice of kernels and return the details
for the one you pick.

It might be this one:
https://bugzilla.redhat.com/show_bug.cgi?id=1039171
CC-ing Jim on it
It was a bit hard to find it - but basically you had to use --network
parameter and if you used a bridge - then it had to be called 'xenbr0'.

This is it, I changed the 'int(val)' to '0' in
/usr/lib64/python2.4/site-packages/grub/GrubConf.py and the f20
guest came up after installation.
Though it now fails to come back up after yum update and reboot:

Thanks, this now works as expected (with the patch applied). This
is the resulting kernel line:
linux (kernel /var/lib/xen/boot_kernel.bfKeqy)(ramdisk
/var/lib/xen/boot_ramdisk.GwQf8f)(args

(though the guest still crashes on reboot as described in my last
email)

I have some more info on this second problem, the first problem is
clearly the same as described in this patch/workaround:
http://xenbits.xenproject.org/gitweb/?p=xen.git;a=commit;h=d513814db6af2b...
Now the system will come back up on reboot, but not if I upgrade the
kernel on the guest (I can upgrade everything else).
Any ideas? it is either that there is some new incompatibility
between kernel 3.11.10 and 3.12.8 on f20, or pygrub on centos5 can't
cope with two kernel entries.

Further info, I did the obvious test here: I installed this new f20
kernel and removed the old f20 kernel entry from the grub.cfg file.
The guest crashes, so I suppose the f20 3.12.8 kernel is
incompatible with centos5 xen.

kernel and removed the old f20 kernel entry from the grub.cfg file.
The guest crashes, so I suppose the f20 3.12.8 kernel is
incompatible with centos5 xen.
Can you please paste the full domU kernel verbose debug output,
so we can see what goes wrong?

Thanks, but I some some help here. I'm starting the guest in
virt-manager but nothing appears in the console, how can I capture
the kernel output?
