[libvirt] [PATCH] qemu: Fix specifying char devs for PPC

[Hong-Hua.Yin at freescale.com]

Hi Cole,

This is a patch similar with your previous patch to fix for ARM.
Do you have any comments on it?

Cindy,
Since you are the main contributor to QEMU driver on PPC, I'll also appreciate your comments.

Best Regards,
Olivia
