[Kimchi-devel] [PATCH] Supports Kimchi on LE systems v3

[Ramon Medeiros]

Changes:

v3:
Create a new entry for ppc64le arch
Create key for keyboard type

v2:

Improve coding by removing duplicated actions
Fix typo

On LE systems, some changes on libvirt xml is needed. The input device
for keyboard is not kbd anymore, the architecture is still ppc64 and the
qemu binary is not qemu-kvm as in the other archs.
