Re: [Openstack] Per host floating ip
I'm currently building up, i did a test setup with 3 machines and it worked. Now i'm doing it again with secure passwords, firewall etc. Btw, i just bought 3 EX 4 servers with a private lan between them using the switch + additional nic option they provide. I was thinking that another solution would be to use failover ip and when i assign an ip to an instance a custom hook calls the hetzner api to change the routing to point the ip to the server which is running the vm. Next step would be to use a shared fs like gluster for vm HA. I was thinking to make a blog post as soon as i get everything working to share how i did the setup.

Re: [Openstack] Per host floating ip
I have tried gluster for live migration but could net get it working. Please post back here if get that working. Instances ran fine with /var/lib/nova/instances on gluster, but live migration would change vm state to migrating and then back to running but still have it running where it was without any errors in the logs.
