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
