why would a newer libvirt be required to get 3.4 compat mode?

but you will fail after that as well - if the first host you joined is 
.el6, the emulation mode for VMs is set to -m rhel65, which the fedora 
host is not compatible with. you first need to change the emulation mode 
to 'pc'.

also, expect bugs on live migration between fedora and .el6 hosts - live 
migration is delicate enough.
