[rdo-users] RHOSP 10 failed overcloud deployment

[Pedro Sousa]

Hi Anda,

some things you could check:

Do you have 2 networks on director (ctlplane and external) and are they
reachable from the overcloud nodes?

Seems to me that you have network issues and that's because you're seeing
those long timeouts.

For "Message: No valid host was found. There are not enough hosts
available" message you could check "/var/log/nova/nova-conductor.log".

Regards
