i have set up my CentOS7+RDO Liberty environment and everything works fine. I would like to get non-shared block storage working; so running:

nova --insecure live-migration --block-migrate  9cc0eaa5-f14b-4ed1-86d3-cfd2453958ce neb0007

results in... nothing! but looking through the nova-compute logs i see:

Live Migration failure: internal error: unable to execute QEMU command 'migrate': this feature or command is not currently supported

my/etc/nova/nova.conf contains:

[libvirt]
virt_type=kvm
block_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE, VIR_MIGRATE_PEER2PEER, VIR_MIGRATE_NON_SHARED_INC, VIR_MIGRATE_LIVE

my /etc/libvirt/libvirtd.conf

listen_tcp=1
tcp_port="16509"
listen_addr="0.0.0.0"
listen_tls=0
auth_tcp="none"

my /etc/sysconfig/libvirtd:

LIBVIRTD_ARGS="--listen"

my rpms:

# rpm -qa | grep libvirt
libvirt-client-1.2.17-13.el7_2.5.x86_64
libvirt-daemon-driver-nwfilter-1.2.17-13.el7_2.5.x86_64

libvirt-daemon-driver-secret-1.2.17-13.el7_2.5.x86_64

any pointers?

I had the same problem, my solution was to add the repository oVirt. Qemu on centos7 repository does not support migrate.

qemu-kvm-common-ev-2.3.0-29.1.el7.x86_64 qemu-kvm-ev-2.3.0-29.1.el7.x86_64

my /etc/libvirt/libvirtd.conf

listen_tls = 0 listen_tcp = 1 tcp_port = "16509" unix_sock_group = "libvirt" auth_tcp = "none"

my /etc/sysconfig/libvirtd

LIBVIRTD_CONFIG=/etc/libvirt/libvirtd.conf LIBVIRTD_ARGS="--listen"

my/etc/nova/nova.conf

virt_type = kvm live_migration_flag="VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_PERSIST_DEST,VIR_MIGRATE_TUNNELLED" live_migration_uri=qemu+tcp://nova@%s/system

i pull the repo from http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm and did an update.

i don't tested block-migrate, i tested live-migrate, previusly configured libvirt with ceph on nova compute nodes.
