libvirt: Acquire TCP ports for console during live migration
During a live migration process we reserve serial ports on
destination host and update domain XML during migration to
use the new reserved ports from destination.
If the migration succeeds we release ports on the source host.
If the migration fails we release reserved ports on the
destination host.

Title:
enabling serial console breaks live migration
Status in OpenStack Compute (nova):
Fix Released
Bug description:
Version: openstack-nova-compute-2014.2.2-1.el7.noarch
Enabling serial console causes the live migration process to fail with
the following error in nova-compute.log:
nova[12362]: 2015-05-14 21:57:21.108 ERROR nova.virt.libvirt.driver [-]
[instance: a4d0bd8f-666e-4606-9e2a-4c583719719e] Live Migration failure:
internal error: process exited while connecting to monitor: Warning: option
deprecated, use lost_tick_policy property of kvm-pit instead.
qemu-kvm: -chardev
socket,id=charserial0,host=1.2.3.4,port=10000,server,nowait: Failed to bind
socket: Cannot assign requested address
qemu-kvm: -chardev
socket,id=charserial0,host=1.2.3.4,port=10000,server,nowait: chardev: opening

The host IP is coming from the proxyclient_address setting which can't
be 0.0.0.0, but even if it is changed to 0.0.0.0 the port number stays
the same and will likely conflict on the destination. If there is no
port conflict the live migration will succeed.
