   VM migrations DO work on stock KVMqemu/libvirt - you are probably referring to a storage-live migrations? That, indeed, does not work. But rarely anyone uses this feature.
   
   While I support the idea to improve things (I've actually read the whole design of this feature, great work by all means!) - I also don't like the fact that stock qemy binaries don't work.
   
   I understand that improvements require moving forward, but I also understand that many production customers will not be happy to see things broken.
   
   I would prefer you open a discussion fore this, on the ML, and let's see what the public have to say - I also support moving to qemu-kmv-ev - but many production users are using stock versions.
