However, when I attempt to create a new VM and attempt to create a new fixed sized Virtual Disk vdi (however tested with object types vdi, vhd, vmdk, hdd, qcow, qed ) object I get the message "Failed to create the hard disk storage /home/buxton/VirtualBox VMs/test/test.vdi" expanding the details gives the information below
If I create a new disk but select Dynamically allocated it will work with any hard disk file type."Could not create the medium storage unit '/home/buxton/VirtualBox VMs/test/test.vdi'.
VDI: setting image size failed for '/home/buxton/VirtualBox VMs/test/test.vdi' (VERR_INVALID_PARAMETER).
