[one-users] problem with getting Live Migration working

[C S Shyam Sundar]

Hello,

I have a problem with getting Live Migration working. Cold Migration works.

The Hypervisor is KVM on CentOS 6.3. I have one master node and two
VMHosts: *oned*,* one1* and *one2*. The oned machine runs OpenNebula 3.6 on
SQLite backend and sunstone. The same machine exposes */var/lib/one* under
NFS. one1 and one2 are hosts configured under oned and mounts /var/lib/one
from NFS. The VMHosts, dummy network, filesystem are under the same cluster.

I have attached the oned.conf, log snippets from oned.log when a cold
migration occurs and when live migration occurs. The error is - " MIGRATE
FAILURE 5 Network action pre needs a ssh stream."

What was tried:
1) changed the options in kvm driver to -l migrate=migrate_local
2) changed LIBVIRT_URI=qemu+ssh:///system in kvmrc ( on both /var/tmp/one
on vmhosts and /var/lib/one in the master node ).

I'm stuck here and any help is appreciated.

Regards, Shyam
