Hi Ajay,

Your slice is currently in a Dead state, and all associated resources have been released.

If you encounter this issue again, please share details of an active slice or VM.

Thanks,

Komal

Hi Arash,

Could you please try deleting the key from the portal and run fablib.verify_and_configure()?

Hi Nirmala,

Could you please try using the fablib from this branch: https://github.com/fabric-testbed/fabrictestbed-extensions/tree/rel1.9.1 ?

nw.get_interfaces() should work now.

I plan to push this main branch Monday. I’ll keep you posted.

Please let me know if this resolves the issue.

Thanks,

Komal

Hi Philip,

Thanks for pointing that out — noted! I’ll discuss internally to see if we can support specifying bandwidth in Mbps via the API.

In the meantime, you could consider using tools like tc to shape traffic at a more granular level to meet your 30 Mbps requirement.

Best regards,
Komal

Hi Ajay,

node.os_reboot() is recommended to be executed only if you are doing CPU pinning or NUMA tuning. This failed because your VM was already in shutoff state. If the intent is to just reboot the VM, please use sudo reboot via node.execute(). Also, what kind of workload is your application/experiment running? We are noticing some kernel level CPU locks on the host where your VM is running. We want to investigate if something from your experiment is triggering this. Could you please share more details about the experiment workload being executed on this VM?

Appreciate your help with this!

Thanks,

Komal

Hi Ajay,

Your VM was in a shutoff state, which I’ve now restored. Could you please share the notebook that outlines the type of workload you’re running on this VM? We’ve observed similar instances with your slices in the past, so having this information would help us identify the root cause of your VMs shutting down.

Thanks,
Komal

Hi Nirmala,

Could you please change the permissions of the key as indicated in the error message using the command below via terminal in your JH container? This shall fix the issue.

chmod 600 /home/fabric/work/fabric_config/Nirmala

Thanks,

Komal

Hi Garegin,

Thank you for sharing your observation. There was performance fix to improve how the interfaces are handled in the fablib. I suspect this may have introduced this issue. I will investigate this and post a fix once ready.

For now, please use the workaround as you suggested. Apologies for the inconvenience.

Thanks,

Komal

We have scheduled maintenance from July 28 to early August. This feature is planned to be rolled out during that period and should be available afterward.

Best regards,

Komal

Hi Suhib,

Issue has been resolved, and slice provisioning is now functioning correctly. Could you please try your slice again?

Thanks,

The Network AM has been restored, and slice provisioning is now functioning correctly.

Thanks,
