- use pinEmulator to pin domain emulator to host cpu
- 2 cases cover config and live flags
- cpulist with '^', '-' and ',' is supported to give multiple
host cpus
Related bug 916493:
pinEmulator and emulatorPinInfo should be simple with required params
https://bugzilla.redhat.com/show_bug.cgi?id=916493
is fixed, so the test can run successfully now.
