Re: [help] Problem loading resources in Flack

Hi Andrea,

There are a couple of known issues with the topology you have described:

 1) the Xen server on IG GPO is overloaded

 2) more importantly, there have been issues using OVS on XEN with other XEN hosts (I'm forwarding this message to geni-users@ so someone with more knowledge can fill you in)

There is a very similar topology available as part of the Intro to OF tutorial [1] which uses OpenVZ for the hosts.

Also in general, 30 minutes is a long time to wait for a topology to come up.  So if it's not green by then, you should probably assume that it's likely to fail.  That said, it should eventually turn red if it fails.

Hope this helps,

Sarah Edwards, GPO

[1] Unfortunately the wiki page is currently down but it will be up a little later: http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/OpenFlowOVS

I believe the same RSpec is listed in the portal as "OF OVS Tutorial with Xen & OpenVZ"

Hello,

I have created an architecture in the Flack, it is basically 5 virtual machines, one of them work as controller, three of them as hosts and one as a switch. The controller and the hosts are using a Ubuntu 12.04 LTS disk image, the switch is using Ubuntu 12.04 LTS with OVS for ProtoGeni (by Niky) disk image. I created the architecture in the flack and I clicked "submit" and I've been waiting for hours for the resources to load, it doesn't change from yellow to green. Apparently the vm machine that is named switch is the one having troubles because its outline is yellow while the outline of the other components is already green (see picture attached). I've tried this in different slices, and in both instageni.gpolab.bbn.com and instageni.stanford.com resources and still nothing. Could you help me this issue?

Thanks in advance,

Hi Andrea,

I just wanted to follow up with you and see if your problem has been
solved, or if you are still having troubles bringing your topology up.

Cheers,
Niky
