[pve-devel] [PATCH qemu-server 0/7] online vm migration to external cluster

[Alexandre Derumier]

This add support to migrate a vm online to an different external cluster.
(This a rework of a previous patch series sent 2years ago)


qm migrate <vmid> <targetremotenode> --migration_type external [--targetstorage monpoolceph_vm] --online


targetstorage is optional, if not defined it's used same storagename than source
targetremotenode is a fqdn host from another cluster. 
(source node must be able to root ssh to target node with public key)

source vm is not deleted currently for safety, just stopped and the migrate lock keeped to avoid
to restart it.


Please review and comment
