[PVE-User] qm live migration with local storage

[boris.tassou at securmail.fr]

Hi,

This is the situation, i have 3 nodes with Proxmox 5 with this specs :
- storage full lvm
- no HA activate
- no shared storage
- 1GB links dedicated to admin/migraiton

I want to migrate some VMs from node 2 (guerech) to node 3 (barbetorte).

Pveversion on node 2 :
https://paste.swordarmor.fr/0bru

Pveversion on node 3 :
https://paste.swordarmor.fr/sN8Z

I use this command to launch the migration :
root at guerech:/etc/pve# qm migrate 700 barbetorte --with-local-disks 1 
--online

When it failed, i have this result :

drive-virtio1: transferred: 34361769984 bytes remaining: 0 bytes total: 
34361769984 bytes progression: 100.00 % busy: 0 ready: 1

I have the space disk available on the node 3. When i launch the live 
migration, the VM is up and online.

The VM conf file :

I see on the forum sometimes it can perform live migration with local 
storage, sometines it's not, i don't know what to think. For example :
https://forum.proxmox.com/threads/live-kvm-migration-without-share-storage.16200/
https://forum.proxmox.com/threads/proxmox-5-0-live-migration-fails.35629/

I don't know where to search or what i need to see.

Can you help me?

Thank you for your time!
