[pve-devel] RFC: vm migration+storage to external/remote proxmox cluster

[Alexandre Derumier]

Hi,
This patches serie implement a new method

qm migrateexternal <vmid> <ip_or_fqdn_of_target_host> -targetstorage <sid>

to allow to live migrate+storage migrate a vm to a remote proxmox cluster,

with a new vmid on the target cluster.

Main differences with classic live storage migration:

- new vmid on target cluster
- src disks on shared storage are also migrated
- src vm && disks are not deleted after the migration. (only stopped)

Please review && comment :)   


(This is only online currently, I'll try to work on offline migration after that,
as it need to implement nbd server out of qemu process)
