Description Andrey Falko 2012-04-02 14:08:52 EDT
Description of problem:
The emulated machine is currently hard-coded and winds up in the database here:

select * from vdc_options where option_name='EmulatedMachine' and version = '3.0';

As a result of a difference between Fedora and RHEL, the name can differ and is annoying to track down for new ovirt users. See the following for further reference:


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

How reproducible:
Run ovirt packages on RHEL-based host

Steps to Reproduce:
1. On a virgin ovirt install, import a VM and try to run it.
Actual results:

> rhel5.5.0  RHEL 5.5.0 PC
> rhel5.4.4  RHEL 5.4.4 PC
> rhel5.4.0  RHEL 5.4.0 PC

Expected results:
Virtual machine starts up
