[libvirt] [PATCH] [libvirt-test-API] Use YABOOT instead of ISOLINUX to create bootable ISO.
Yaboot is the bootloader of PowerPC (ISOLINUX on AMD64/x86 systems, yaboot on PowerPC), so should change the yaboot.conf firstly,then use mkiso command to create bootable ISO.

Whether we consider to rewrite it in python language and add it as a function into utils module instead of a shell script, in addition, I don't like 'if..else' in shell, if we will support other bootloader in the future, we must add a new 'else' branch in ksiso.sh, it hasn't a better expansibility. I'd like to use python 'getattr' as a dispatcher to deal with this kind of case. if we need to add a new bootloader support, just need to add a new function/interface, you don't need to change original codes.

Currently, the script is fine to work and easy to maintain. Python wrap will make it complex. let's just keep it for a while. Guannan Ren
