Hi,

I am new to xen development. I am trying to add a feature to the live
migration process. Instead of depending on the expected downtime and
transfer rate, I want to be able to manually trigger the stop-copy phase of
a live migration.

I am totally lost in the code. Can someone please point me where I should
start looking to implement this feature.

Hi All,

I am working on live migration for some images(migrate images from one
pool of one cluster, to a new pool in "another" cluster).

Do you have any experience or suggestion on how to do it?

Thanks
Pan

Proxmox VE can use the qemu feature "move_disk" to do this. If you are
also using qemu-kvm, you could also do that from the qemu monitor. It
lets you move a disk to another storage place (eg. from NFS to ceph
librbd and back which I tested) without restarting the VM.

Hi Peter and All,

Thanks for reply.

But I am not using qemu-kvm, the use model is: there are many docker
containers built on top of nbds. Each nbd is mapped to an image by
using rbd-nbd map.
