[Qemu-devel] Where is the VM live migration code?

[Jidong Xiao]

Hi,

I saw this page:

http://www.linux-kvm.org/page/Migration.

It looks like Migration is a feature provided by KVM? But when I look
at the Linux kernel source code, i.e., virt/kvm, and arch/x86/kvm, I
don't see the code for this migration feature.

So I wonder where is the source code for the live migration? Is it
purely implemented in user space? Because I see there are the
following files in the qemu source code:

migration.c  migration-exec.c  migration-fd.c  migration-rdma.c
migration-tcp.c  migration-unix.c

If I wish to understand the implementation of migration in Qemu/KVM,
are these above files the ones I should read? Thanks.
