Description Ken Sugawara 2013-09-27 06:42:02 EDT
Description of problem:
koan creates an i386 guest even if the install tree of the ks profile given is one for x86_64. As a result, the guest fails to install.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create a kickstart profile on Spacewalk or RHN Satellite for an x86_64 OS (rhel-x86_64-server-6 for instance)
2. Try to install an instance of the above profile with koan:

# koan --server=satellite.example.com --virt --profile=sample-profile:1:YourOrganization


Actual results:
Guest starts but fails to install.

# koan --server=sat.34x27.org --virt --profile=puppet-clients:1:RedHatConsultantsGPS-APAC

Note the '--arch i386' argument given to virt-install above.

Expected results:
Ideally, koan should extract the architecture from the URI to the kickstart tree, or at least there should be a way to instruct koan to create a 64-bit guest instead of 32-bit one (or maybe it should defaults to creating 64-bit guests since 64-bit guests should be able to run and install 32-bit OSes?).

Additional info:
I took a look at koan source and straced it. It does not seem to get the arch by running 'uname -m' as written in the app.py, which implies that it sets ANCIENT_PYTHON to 1 whereas the actual python version is not quite ancient (2.7.3-13.fc18). Maybe the way app.py detects ancient versions of python no longer works with newer python versions?

I've been doing some diggin' on this, and it turns out this is not a koan bug, but there is a dict entry 'arch':'i386' in the profile data koan receives from cobbler via xmlrpc (that happens to be Satellite 5.4).

Now I have to figure out how to override this parameter for my guest profile...
