CML lab wouldn't launch

[JulieYi]

I am trying to launch CML lab but it keeps giving me Torque cannot launnch error messages.

You would need to check a few things in order to validate why you're getting this message:

Firstly, have you enabled nested virtualisation in the BIOS/hypervisor? CML requires nested virtualisation in order to spin up virtual machines (i.e. network devices) inside of CML.

Secondly, I would check your resource utilisation on your machine to ensure that you've got enough resources to launch CML.

Lastly, you might have to restart the VM. If nothing else works, you might have to rebuild the VM from scratch.

It would be good to understand if this error occurs when trying to launch a particular lab, or if it occurs when the program boots?

There were some errors on the DevNet sandboxes the last week (there was a banner message) and now is on Maintenance. I will try once there are no banners and the maintenance is done. Sometimes takes some days, so check every once is a while
