Live-migrate outside of cluster

I have few PVE nodes and some times I need to transfer VMs between them but they are not in a cluster.
Does anyone know a trick on how to live-migrate a VM between nodes which are not in a cluster?
 
This is currently not possible. Cross-cluster migration and useability is on the roadmap, but not available yet.
 
you need to create an api token on destination cluster, then on source cluster
exemple:

Code: 
qm remote-migrate <srcvmid> <dstvmid> 'apitoken=PVEAPIToken=root@pam!migrator=efgD9b785-f0f3-47bb-8553-26F1166c6ed0,host=remotehost.fqdn' --target-bridge vmbr0:vmbrX,vmbr1:vmbry --target-storage localstorage:deststorage --online


works online only currently

Certain storage combinations only work online (e.g. our RBD plugin doesn't implement offline export/import currently), but others work just fine offline (e.g. ZFS -> ZFS, dir -> dir).

Stefan_R, et alia:

The original poster (OP) was asking about several nodes that were entirely not clustered at all and the answer given was regarding "cross-cluster" (meaning two different clusters exist and you wish to move betwixt the two). I am curious to know if the OP's original question is actually being answered?

My question of course has not been asked yet and that is concerning the migration (live or not-live) betwixt a cluster of nodes and a singular node not part of any cluster at all.

Thanks in advance!

All,

Please allow me to proffer this hypothetical:

If one has two different clusters each with 3 nodes ("cluster1" and "cluster2") along with a single un-clustered node "node-unclustered". Is there a "Datacenter view" that will show you all of cluster1 and its nodes, cluster2 and its nodes, and the unclustered node?

Cross-cluster migration is one of the steps that needed to be taken to make something like that usable. A datacenter manager is planned (can't give any ETA though): https://forum.proxmox.com/threads/multi-datacenter-management.66830/page-2

Thank you. It's the middle of night here and I am going back to bed.

I tried to do a test migration from one cluster to another:

Code: 
qm remote-migrate 2644 2644 apitoken='PVEAPIToken=xxxxxxxxxxxx',host=10.0.3.106,fingerprint=XX:XX:XX,port=8006 --target-storage osdpool --target-bridge vmbr0:vmbr0 --online

But always show an error "remote: storage 'osdpool' does not exist!"
The target name exists.

What I'm doing wrong ?

Thanks

does the apitoekn have acl/permissions on the storage ?
