And there you likely have your problem. Multi-head support first got added to the agent in 6.4, and the official qxl drv in 6.4 is: xorg-x11-drv-qxl-0.1.0-4.el6

I tried to reproduce this with the official 6.4 agent + qxl driver, and failed -> closing.

Feel free to re-open if you can reproduce with the 6,4 qxl drv,
