*
* Large variations cause migration to fail for more than one
* consecutive value of the "-smp" maxcpus option.
*
* For small variations of the kind caused by different iasl versions,
* the 4k rounding usually leaves slack. However, there could be still
* one or two values that break. For QEMU 1.7 and QEMU 2.0 the
* slack is only ~10 bytes before one "-smp maxcpus" value breaks!
*
* 6652 is valid for QEMU 2.0, the right value for pc-i440fx-1.7 on
* QEMU 1.7 it is 6414. For RHEL/CentOS 7.0 it is 6418.
