Hi @Bern_G, Quick question for you on your Virtualbox situation. What kind of disk did you set it up with (i.e., SCSI, SATA, PIIX4, etc.) in the virtual machine settings. We recommend the PIIX4 or some other IDE variant for the virtual box environment. The specific problem you're having is very common with SCSI or SATA drives
Seems that CSP on VirtualBox will only boot in rescue mode. Otherwise it can't find anything in /dev/cs.
Don't delete and recreate the disc. Change its type to PIIX4. Go into settings, change from Basic to Expert, click storage and then change the type like in the pic i attached
For the OP solution, open VirtualBox, go to settings > storage and drag the disk vmdk file from the SCSI controller up to the IDE controller. Start the vm and it should boot properly without issue.
For those who have converted the vmdk file to qcow2 file, run openstack cli command:
openstack image set --property hw_disk_bus=ide <image ID>
