[Qemu-devel] [RFC kernel 0/2]A PV solution for KVM live migration optimization

2016-03-03 Thread Liang Li
The current QEMU live migration implementation mark the all the guest's RAM pages as dirtied in the ram bulk stage, all these pages will be processed and that takes quit a lot of CPU cycles. >From guest's point of view, it doesn't care about the content in free pages. We can make use of this fact
