Hi Matthew,

It looks like a UUID is missing or corrupted in the Django data model of Bumblebee while creating a volume record for a new VM.

If we take a look at the model of a Bumblebee volume, we notice that a valid UUID for the flavor field is required (see [1]). During the VM creation, a new volume record is created where the volume's flavor field is set to the resolved UUID of the default flavor from a desktop type (see [2]). Setting an invalid flavor UUID could be the cause here.

When setting up bumblebee, did you specify valid flavor names (existing ones from OpenStack) for all desktop types?

To check the volume records in the database and adjust them if necessary, you can simply use the Django admin site. There you can view the entire data model of Bumblebee and all stored records graphically.

Hello,

I'm trying to install the VDI project on my Ubuntu 22.04 LTS Desktop VMware workstation. So I chose Bumblebee(https://github.com/NeCTAR-RC/bumblebee) and went through several steps like configuring the devstack, installing docker, and Bumblebee project.

And then, I tried to create a virtual desktop from Bumblebee and I got the below error:

ValueError: badly formed hexadecimal UUID string

Anybody has already experienced a similar issue or does anybody have any idea to solve this problem? Then please help me.

Looking forward to hearing from you.

Much appreciated. Matthew
