Hum..if the live migration is not happening on a shared storage, then I think it is best to have offline migration copy to image and hook up to the destinated server instead, this is a short-cut path I suppose.

Hope that helps. As far as I know (and it definitely worked in CentOS 6 and from CentOS 6 to CentOS 7) no guest tools are needed. But I tried it nevertheless: did not work :( Live migration with shared storage works fine but in my case I need to do live migrations without shared storage (in order to free running hosts to upgrade their OSes and setup shared storage) I suspect either that the qemu-kvm binary from qemu-kvm-ev-2.6.0-28 is missing this feature or it is called without a needed option. Comparing running qemu-kvm processes on CentOS 6 and CentOS 7 I can see that those on CentOS 6 have -enable-kvm on the command lime but those on CentOS 7 have not. How can the qemu-kvm binary be checked to see if the feature is enabled?
