Re: [Xen-devel] [PATCH 6 of 8 [RFC]] libxc: introduce xc_domain_move_memory

Is this solution intended to be the final one?

This might be okay for a domain with less than 1GB of memory, but I see
problems for really huge domains. The needed time to copy the memory might
result in long offline times. For this case something like live migration
(optional?) would be a better solution, I think.
