<font face="Default Sans Serif,Verdana,Arial,Helvetica,sans-serif" size="2"><p>Hi,</p><p><br></p><p>I have a multinode OpenStack kilo setup with 2 compute nodes, a
controller and a network node. I am trying to migrate a Vm from host to
the other, but there is a migration failure and the VM stays on the same
host.</p> <p>I can ping between the compute nodes, and I have set libvirt to listen mode. Using the following steps:</p> <ol><li>Modify /etc/libvirt/libvirtd.conf.
before : #listen_tls = 0
after : listen_tls = 0</li></ol> <p>before : #listen_tcp = 1
after : listen_tcp = 1</p> <p>add: auth_tcp = "none"</p> <ol><li><p>Modify /etc/init/libvirt-bin.conf.
before : exec /usr/sbin/libvirtd -d
after : exec /usr/sbin/libvirtd -d -l
-l is short for –listen</p></li><li><p>Modify /etc/default/libvirt-bin.
before :libvirtd_opts=" -d"
after :libvirtd_opts=" -d -l"</p></li><li><p>Restart libvirt. After executing the command, ensure that libvirt is successfully restarted.
$ stop libvirt-bin && start libvirt-bin
$ ps -ef | grep libvirt</p></li></ol> <p>Nova compute(Compute) logs:</p> <p>2015-07-30
