Open Stack

Hi:all? ???I'm testing juno version now just follow the guide of <<openstack-install-guide-yum-juno.pdf>> from docs.openstack.org.? ? ?Today I go through the Live migration issue:? ? ?When I test the Block Migration(by: ?nova live-migration --block-migrate c4c5fbfa-8faa-4a01-b260-6b556aeafd07 compute01)?I encountered the following error message:? ???(Live Migration failure: internal error: unable to execute QEMU command 'migrate': this feature or command is not currently supported.)
? ? ?I googled for it and get the solution:?https://www.redhat.com/archives/libvirt-users/2014-December/msg00008.html?,and I follow the advise to yum install qemu-kvm-rhev,and restart libvird and openstackservices,but the error still there.
? ? When I test the?Volume-backed live migration(by:?nova live-migration d720f8ef-dd9a-41c9-ab81-54ef1cd05fd3 compute01,d720f8ef-dd9a-41c9-ab81-54ef1cd05fd3 is the vm uuid which residented on cinder volume.)?I encountered the following error message:? ? (Returning exception compute01 is not on shared storage: Live migration can not be used without shared storage.)
? ? And I googled for it and find a bug fix:?https://git.openstack.org/cgit/openstack/nova/commit/?id=5a0711dbffe3d68ee9be39c85307b19ea5efee7a?,and I replace the old driver.py(in?/usr/lib/python2.7/site-packages/nova/virt/libvirt/) with the
new one (whose md5sum is:bb65bf9f97b5c8b5060df8a0d909b0ff  driver.py),but the error remains.
? ? Is there any thing I missed? I was able to live migration on Havana version before.(all the configs are followed the?suggestions?of :https://lists.launchpad.net/openstack/msg24036.html)?
? ? Any advice will be?appreciated! Thanks a lot.? ?
