This document covers the most frequently asked questions for the EOSC EU Node Virtual Machines service.
I'm having problems connecting to my newly created instance. What could it be?
Check that you do not have more than ONE interface connected to the instance. Connecting more than one network interface to an instance is not recommended. In Safespring the gateway address is provided by default and in PSNC it is possible to configure two networks with different routers that provide the default gateway for the instance with DHCP. Having two interfaces and two default gateways will cause a conflict in the instance which to use and cause asymmetric routing. Therefore it is not recommended.
You should also check that you have created the correct Security Groups and that they are applied to the instance, by picking "Edit Security Groups" in the dropdown meny at the instance row.
I see different kinds of flavors. Which one should I use?
In both Safespring and PSNC there are different kind of flavours with different configuration of CPU, memory and storage. They can mainly be grouped into two different groups: flavours with local ephemeral storage and flavours without. You can see if a flavours comes with local storage or not by viewing the "Root disk" column in the flavour listing. If it says zero, the flavours does not have local storage storage, and if it has a number other than zero it has local storage.
Flavours without ephemeral storage have to be booted from a volume. How to do this is described in the user scenarios.
Flavours with ephemeral storage have to be booted from an image. This is also described in the user scenarios.
