I am dropping this mail to you because I came across from this site: http://www.linux-kvm.org/page/Migration , it is said that whole dirty pages or system memory transfer is possible during VM migration in KVM. As states belowHi,Can any one please guide me how I can copy the system memory Page tables to dirty pages during the VM migration from one host to another host (Both host are in same subnet) in NUMA architecture node (Basically looking for some standard API). I am developing an application and this is one of the main requirement to do.

- Guest continues to run
- Bandwidth limitation (controlled by the user)
- First transfer the whole memory
- Iteratively transfer all dirty pages (pages that were written to by the guest).
