mmm, maybe an ssh tunnel problem.

Myself, I always disable migration through ssh tunnel, maybe that's why it's works for me.

try to add

migration_unsecure: 1

in /etc/pve/datacenter.cfg

this will do live migration directly between both qemu process, without ssh encryption.

hi, Alexandre 

在 2015年10月13日,下午8:20,Alexandre DERUMIER < aderumier at odiso.com > 写道: 

migrate vms (do it for each vmid) 

# qm migrate <vmid> <target_proxmox4_server> -online 

(migrate must do done with cli, because pvestatd can't start without systemd, so gui is not working) 

Very unfortunate! (: 

got new error.
