From qemu-kvm-0.12.1, kvm has the function about live migration with non-shared storage. But I don't know how to use it. In the qemu monitor, "migrate -d tcp:10.1.10.42:444" which is based on shared storage is going well. I don't know how to use the command of "-b or -i" or maybe I don't know the correct format of uri.

the source and destination system is Fedora-13, and the version of kvm is qemu-kvm-0.12.3.

Migration with storage is not supported in libvirt until 0.8.2. The version you are trying with F13 is too old. With virsh you would add the --copy-storage-all or --copy-storage-inc flag to 'migrate'

When I use the "migrate -d -b tcp:10.1.10.42:4444", the qemu monitor don't show nothing. When I use "info migrate",there shows "migrate status: failed". I don't know why? I hope someone who used this command successfully would help me, thank you.

If you're just using QEMU directly outside libvirt, then you're better directing questions to qemu-devel mailing list Regards, Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|
