in func 'libxlDomainRestoreFlags',it doesn't use 'libxlFreeMem' to
check
whether there are enough memory before restoring the vm!It just restore the
vm anyway,until xenlight found no enough space in the middle of the process
Is this a bug?or It's designed this way by purpose?Thanks in advance.

libxlDomainRestoreFlags doesn't call libxlFreeMem directly, but it does
call libxlVmStart, which afaics calls libxlFreeMem when restoring.
Have you seen restore fail without a helpful error when there is
insufficient memory to host the domain?
