[one-users] Migrate error with OpenNebula 3.4.1 using KVM hypervisor on Ubuntu 12.05 box

[Duverne, Cyrille]

Hello Thai,

Could you give the output of : ls
-lArth /var/lib/one/var//datastores/0/8/disk.1 ?
Another thought : Is "oneadmin" part of the "libvirt" group ?

Cheers

Dear,

I am trying to live migrate from KVM host to another KVM host but I
always catch an error message which I quote below. Does anyone know
the reason and how to solve this problem ?
