pacemaker_remote will try to bind to IPv6 addresses first, and only if
that fails, will it bind to IPv4. There is no way to configure this
behavior currently, though it obviously would be nice to have.

The only workarounds I can think of are to make IPv6 connections work
between the cluster and the remote node, or disable IPv6 on the remote
node. Using IPv6, there could be an issue if your name resolution
returns both IPv4 and IPv6 addresses for the remote host; you could
potentially work around that by adding an IPv6-only name for it, and
using that as the server option to the remote resource.
