Chunhe Li 33445ce844 openvswitch: Delete port if it exists while adding a new one
If the openvswitch service is stopped, and is followed by destroying a
VM, the openvswitch bridge translates into a state where it doesn't
recover the port configuration. While it successfully fetches data
from the internal DB, since the corresponding virtual interface does
not exists anymore the whole recovery process fails leaving restarted
VM with inability to connect to the bridge. The following set of
commands will trigger the problem:

virsh start vm
service openvswitch-switch stop
virsh destroy vm
service openvswitch-switch start
virsh start vm

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
