Re: [openstack-dev] [Fuel] How to auto allocate VIPs for roles in different network node groups?

Hi, btw, we should also take into account the possibility to share networks in Fuel-8.0. So if cluster is configured with shared public and management networks then moving controllers into different network node groups (racks) is fine and it will work out of the box [0] and we should not forbid su

2016-01-15 Thread Aleksandr Didenko
Hi, We need to come up with some solution for a problem with VIP generation (auto allocation), see the original bug [0]. The main problem here is: how do we know what exactly IPs to auto allocate for VIPs when needed roles are in different nodegroups (i.e. in different IP networks)? For example '
