Test on i386 and x86_64 PV guest with below memory/cpu set:
512M UP/SMP
16G UP/SMP
32G UP/SMP
70G UP/SMP
128G UP/SMP

Cases including:
1. Guest startup/pause/unpause/reboot/shutdown
2. mem-set/mem-max, the knownissue rhbz#523122 still exists
3. regular/live/ping-pong migration
 The live migration with 128G memory will get error, a seprated bug rhbz#728877 to trace it.
