known issue, on F19 please enable fedora-virt-preview repo, update "libvirt*"
and retry
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.
