This is happening, I believe because koan's DL'ing from:
url=http://server.internal.net/cobbler/images/fedora8/initrd.img
rather than,
url=https://server.internal.net/cobbler/images/fedora8/initrd.img
Checking, if I nav to:
links http://server.internal.net/cobbler/images/fedora8/
I see,

which is what's in those "errant" koan DL's ...
Whereas if I instead nav to:

i see as expected,

Bottom line ... koan's NOT getting files via the required https://....
And, this, of course, would explain the "invalid kernel" messages I've
been seeing.
Now, the question is config change in koan/cobbler? apache? or a koan
source problem?
HTH,
Jimmy
-------------------------------------------------------------------------------
So to summarize, you have port 80 configured to be HTTPS and you have
shut http:// off?
To get things going you'll need to turn it back on in the Cobbler
server. The address of the cobbler server and the port is configured
in settings, but the URLs
generated will be http://. It does not need to be port 80, but if
it's not, you need to change the port value in /var/lib/cobbler/settings.
This probably explains both your transfer error and the XMLRPC messages.
It would be possible to allow cobbler to generate https:// URLs, though
there is not much point in doing so -- Anaconda itself does not support
authentication.

Michael,
I decided to step away from it myself, and have someone else here
setup a new/clean box. again, vanilla f8 + apache.
They've pulled latest git heads of cobbler/koan.
Now, @ their "koan ...",
koan --virt --virt-name=test --server=http://server3.internal.net
--profile=f8test
--virt-path=/dev/VG03/test --autonet --nogfx
Could not communicate with http://server3.internal.net:25151
checking @ server3
service iptables status
iptables: Firewall is not running.
service ip6tables status
ip6tables: Firewall is not running.
and,
telnet server3.internal.net 25151
Trying 10.0.0.203...
Connected to server3.internal.net.
Escape character is '^]'.
has something changed?
-------------------------------------------------------------------------------
Is cobbler check clean? Is cobblerd running?
-------------------------------------------------------------------------------
yes to both.
cobbler check
No setup problems found
Manual review and editing of /var/lib/cobbler/settings is recommended
to tailor cobbler to your particular configuration.
Good luck.
service cobblerd status
cobblerd (pid 7761 7760 7759 7758) is running...
-------------------------------------------------------------------------------
Can you actually telnet to that port from the remote box?
FYI: Q&A should go to the public list.
-------------------------------------------------------------------------------
yes. that's what the above,
telnet server3.internal.net 25151
Trying 10.0.0.203...
Connected to server3.internal.net.
Escape character is '^]'.
was. sorry, did not make it cleat that the telnet was from a remote.
