[PATCH] Support for autostarting qemu/libvirt virts

Greetings all! This is my first patch to the project, hopefully the first of many! This patch provides the ability to auto start any VM that registers itself in libvirt. In the code it works on virts with virt_type of 'qemu'. A pause was required for the lookupByName(domain_name) call to succeed. In my testing lookupByName was consistently unable to locate the domain unless a brief pause was forced before the lookup. The current behavior should the lookup fail is to throw an InfoException. This patch closes https://fedorahosted.org/cobbler/ticket/408 All code is based off 65bf5c1fa.... from the FedoraHosted git repository. I look forward to your feedback and working with everyone more in the future. --- Tim 'Shaggy' Bielawa http://peopleareducks.com
