Thanks Razique for taking up this one. Libvirt version on both Compute hosts: $ libvirtd --version libvirtd (libvirt) 0.9.2 $ virsh --version 0.9.2
Here are my libvirtd.conf details: listen_tls = 0 listen_tcp = 1 unix_sock_group = "libvirtd" unix_sock_rw_perms = "0770" auth_unix_ro = "none" auth_unix_rw = "none" auth_tcp = "none" Thanks & Regards, Unmesh Gurjar | Lead Engineer | Vertex Software Private Ltd. | w. +91.20.6604.1500 x 379 | m. +91.982.324.7631 | unmesh.gur...@nttdata.com<mailto:unmesh.gur...@nttdata.com> | Follow us on Twitter@NTTDATAAmericas From: Razique Mahroua [mailto:razique.mahr...@gmail.com] Sent: Wednesday, April 11, 2012 7:33 PM To: Gurjar, Unmesh Cc: openstack@lists.launchpad.net Subject: Re: [Openstack] Issue in KVM block migration Hi, it looks like the user under which libvirt is running doesn't have the rights to manage server's IF.
