...nt of unused pages by allocating them: 1) It's expected that live migration shouldn't affect the things running inside the VM - take away all the free pages from the guest would greatly slow down the activities inside guest (e.g. the network transmission may be stuck due to the lack of sk_buf). 2) The hint of free pages are used to optimize the 1st round memory transfer, so the hint is expect to be gotten by the hypervisor as quick as possible. Depending on the memory size of the guest, allocation of all the free memory would be too long for the case. Hope it clarifies the use case...
