When I try to create a fixed disk for a new virtual machine using the GUI (guest operating system is Linux 64-bit), I get the following error: Could not create the medium storage unit '/home/.../VirtualBox VMs/HDNode1/HDNode1.vdi'. VDI: setting image size failed for '/home/.../VirtualBox VMs/HDNode1/HDNode1.vdi' (VERR_INVALID_PARAMETER).

Both result in the same failure. - I'm trying to create a 20.00 GB fixed disk. There is 418 GB available on the host system. ",defect,closed,virtual disk,VirtualBox 5.1.16,duplicate,,,Linux,Linux
