= CPU capability problem =
Because CRIU allows to live migrate containers (see [[Live migration | Live_migration]] for details) it might happen that CPU a container has been ran on differ from the target CPU. For typical programs this might be not a problem but if a program get compiled with optimization which use a particular CPU feature (say AVX instruction and etc) the lack of the feature on a destination machine will lead to execution exception in a best case.
Thus there should be a way to test if destination machine is capable of running container being migrated.
