Hi everyone,
I'm working with SUSE OpenStack Cloud 5 and have a question regarding the network configuration. I'm not sure if this is the right mailing list, but I'll give it a try. We have a three node environment, 1 Admin node (SLES11-SP3),1 Control node (SLES11-SP3) and 1 Compute node (SLES12). After some problems we managed to set up a working cloud environment, except the network configuration is not quite clear yet. We deployed the Neutron barclamp with linuxbridge and have our physical network divided into VLANs. So the question is: how is the whole network setup supposed to be? What am I supposed to see on Control and/or Compute Node?
You can find details information here [1] .
If I understand the documentation correctly, I should be able to log into a running instance via ssh. But this only works, if we manually set up a vlan on the compute node and attach it to the corresponding bridge (floating network), but this configuration only exists until the next reboot. I don't want to ask too many questions, so I would be really happy if someone could explain to me, what I should see on the nodes. A similar question is here: https://forums.suse.com/showthread.php?6490-running-instances-in-external-VL....
I'm not very familiar with VLANs, bridges etc., so please don't answer to complicated for me ;-)
To be able to ssh in a VM from outside the cloud you have to assign a floating up to the VM and then ssh using the floating ip. You can find the right commands to use there [2]. You can also use horizon to do that. These are the basic operations: 1) create a router 2) set it as a gatway 3) connects the network that the VM belongs to to the router 4) create a floating IP 5) assign it to the VM Make sure that the security group assigned to the VM allows TCP on port 22 otherwise ssh won't work. cheers, Rossella
Thanks a lot!
Best regards, Eugen
