ubuntu 14.04 uses too old version libvirt. try to upgrade libvirt or update operating system.

I have the same error on CentOS 7.6

What is the version of libvirt? You can get with virsh version
You can install qemu-kvm-ev an update libvirt.

Add libvirt repo and qemu-kvm-ev

The problem is libvirt version. need update to ubuntu 16.04 - no updates on ubuntu 14.04 and Centos 7 need use EPEL repository.
