Hello Shyam,<div><br></div><div>thanks a lot for the feedback and for letting us know it's working again. I think this must be an issue of the libvirt version, and that the default configuration supplied with OpenNebula is not working out of the box for this OS version.</div>
<div><br></div><div>We will make some tests and probably update the documentation.</div><div><br></div><div>By the way, would you mind sending us the libvirt version you're running.</div><div><br></div><div>Thanks again!</div>
<div><br></div><div>cheers,</div><div>Jaime </div><div><br><div class="gmail_quote">On Thu, Aug 16, 2012 at 9:41 PM, C S Shyam Sundar <span dir="ltr"><<a href="mailto:csshyamsundar@gmail.com" target="_blank">csshyamsundar@gmail.com</a>></span> wrote:<br>

<div><font face="courier new, monospace">I have a problem with getting Live Migration working. Cold Migration works.</font></div>
<div><font face="courier new, monospace"><br></font></div><div><font face="courier new, monospace">The Hypervisor is KVM on CentOS 6.3. I have one master node and two VMHosts: <i>oned</i>,<i> one1</i> and <i>one2</i>. The oned machine runs OpenNebula 3.6 on SQLite backend and sunstone. The same machine exposes <i>/var/lib/one</i> 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.</font></div>
<div><font face="courier new, monospace"><br></font></div><div><font face="courier new, monospace">I have attached the oned.conf, log snippets from oned.log when a cold migration occurs and when live migration occurs.
