[libvirt-users] Migration error

[zorgman]

Hi,

I'm trying to migrate a VM from one libvirt 0.7.6-1 (qemu-kvm 
0.11.1+dfsg-1) to another libvirt 0.7.6-2 (qemu-kvm 0.11.1+dfsg-1) 
connected with SSH , i have followed pre requite (same shared, same 
path, same network conf ...) . But when i migrate , i have following 
error : operation failed:

/migration to 'tcp:x.x.x.x:49157' failed: migration failed
DETAIL :

Unable to migrate guest:
 Traceback (most recent call last):

/on the destination libvirt i can see in syslog :

/in the destination libvirt vm log i can see the cmd running by migration:
