Bug 1018693

Description of problem:
--------------------------
I recently run kvm unit test (using run_tests.sh with default unittests.cfg) with upstream qemu on latest RHEL6.5 host, there are 3 cases get stuck, 2 cases fail.

I am not sure whether this is a kvm bug, or kvm unit test problem, or i run kvm unit test wrong, i only modify run_test.sh and x86_run script a little bit to separate log file for each case, and i use upstream qemu for i was told in RHEL6 testdev device in our internal version may not guarantee to work, so feel free to change the component or close if this is notabug.

BTW, the "-display none" command does not exists, i have to remove it from script or it shows all cases pass but don't run them at all.
