I have read these articles: https://wiki.openstack.org/wiki/OSSN/OSSN-0007 https://www.ibm.com/support/knowledgecenter/en/linuxonibm/liabp/liabpkvmsecsrmsasl.htm My current conf is /etc/libvirt/libvirtd.conf: listen_tls = 0 listen_tcp = 1 auth_tcp = "sasl" And now I try : nova live-migration --block-migrate 4309758f-2e66-4c66-bcbb-5f5ee33956ad ip-10-8-8-232.clouds.com I found error on the src hv : Live Migration failure: operation failed: Failed to connect to remote libvirt URI qemu+tcp://ip-10-8-8-232.clouds.com/system: authentication failed: Failed to start SASL negotiation: -4 (SASL(-4): no mechanism available: No worthy mechs found) I try it with virsh ,it worked : root at ip-10-8-8-243:/var/log/nova# virsh -c qemu+tcp://ip-10-8-8-232.clouds.com/system Please enter your authentication name: admin Please enter your password: Welcome to virsh, the virtualization interactive terminal.
