Description
After I enable the Synthetic CPU option on a VM using IMachine.setCpuProperty(), VBoxManage properly reports that Synthetic CPU is enabled, but /proc/cpuinfo in the guest does not change. The reason appears to be that Console::configConstructor() places the CFGM node at /SyntheticCpu, but CPUM expects the node at /CPUM/SyntheticCpu. Adding an ExtraData key to the machine configuration:
VBoxInternal/CPUM/SyntheticCpu -> 1
indeed causes the guest's /proc/cpuinfo to report the synthetic CPU.

Thanks for the report (and the fix on vbox-dev). The fix will be included in the next maintenance release.
