Can you show me your /etc/global.yml profile？
I need more information.

I can't fully understand where your issue is.
kolla_internal_vip_address and kolla_external_vip_address should not be pingable from any node before deployment.

This is just because the IP in that variable is the IP which keepalived will assign to load balance.
Of course, the IPs need to be in a network range pingable from other nodes, but not active before deployment.

The precheck ensures if the IP is used by other node, if is used the task fails, which is the expected behaviour to avoid network conflicts.

If my understanding of your issue is wrong, paste /etc/kolla/globals.yml and error logs as @zhubingbing requested.

If more help is needed, take around #openstack-kolla irc channel, a lot of people will help you.
