rhel6: qemu live migration port conflicts with other users of ephemeral port(s)

Solution Verified - Updated -

Issue

We experienced a live migration failure on a RHEL6.5 KVM host. The failure occurred because the port selected to use for the live migration was already used by other process.

Environment

  • Red Hat Enterprise Linux (RHEL) 6, minor releases before 6
  • libvirt
  • qemu
  • live migration
