Chris, this sounds good. So, over the weekend I cloned the repo and quickly ran an
rpmbuild and installed 'oz' rpm.
This is the standard TDL I used:
---------------------------------------------------------------------------
kashyap@test1$ cat f14x86_64.tdl
<template>
<name>f14jeos</name>
<os>
<name>Fedora</name>
<version>14</version>
<arch>x86_64</arch>
<install type='url'>
<url>http://download.fedoraproject.org/pub/fedora/linux/releases/14/Fedora/x86_64/os/</url>
</install>
</os>
<description>Fedora 14</description>
</template>
---------------------------------------------------------------------------
This was the command line I gave to generate JEOS.
----------------------------------------
$ sudo oz-install -d 4 f14x86_64.tdl
----------------------------------------
The install fails by "Timed out waiting for install to finish" (thrown by `Guest.py` ?):
----------------------------------------
.
.
.
DEBUG:oz.Guest.FedoraGuest:Waiting for Fedora14x86_64 to finish installing, 10/1200
------------------------------------------
I looked at the PNG it generated, and it says :
------------------------------------------
"Cannot retrieve repository(repomod.xml) for repository:
anaconda-InstallationRepo-201010211827.x86_64. Please verify it's path and try again'
---------------------------------------------
I guess this is incorrect. Because I'm very sure(& rechecked) the 'repomod.xml' does exist
in the url(mentioned in f14x86_64.tdl). And using the very same url I do a lot of
unattended network installs via virt-install and kickstart.
Am I missing anything trivial here? I didn't dig much into oz python classes. Will see if
I can get to that over the next weekend.
Thanks,
Kashyap Chamarthy
