What is the configuration on your compute nodes? Do you have a timeout
set for live migration? Do you have post-copy or auto-converge enabled?
What version of libvirt and qemu binaries on those nodes?
I'm going to mark this as invalid per a support request until there is
more information to help debug this or you've gone through those docs on
configuring the nodes for live migration timeout actions.
