I was reading the API reference for the libvirt, when I came across the function? virDomainMigrate and virDomainMigrate2. I am unable to find the difference between the two. Can someone please tell the difference in the application of the two? -- Abhishek

Greetings, I was trying to understand the flow of Migration Code in libvirt and have few doubts: 1) libvirt talks to QEMU/KVM guests via QEMU API. So overall, in order to manage QEMU/KVM guests I can either use libvirt (or tools based on libvirt like virsh) or QEMU monitor. Is it so? 2) Since libvirt is Hypervisor neutral so actual migration algorithm(precopy or postcopy) is present in the

libvirt-ocaml is used only by virt-v2v, so move it to this repository, instead of having it around in the common submodule. The removal from common will happen later.

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not
