Could not create the medium storage

[Xerxes]

I've installed VirtualBox 5.1.16 r113841 (Qt5.5.1) on a new installation of Ubuntu 16.04.2.

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).

Result Code: VBOX_E_FILE_ERROR (0x80BB0004) Component: MediumWrap Interface: IMedium {4afe423b-43e0-e9d0-82e8-ceb307940dda}

I see that this is a duplicate of Ticket #16464, but I have additional information.

• I've tried using a directory that exists and one that does not. 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.

Some additional information:

• I also tried using a directory that does not have spaces in it. Same error.
• I've verified that I have write access to the directory.
• If I create a dynamic disk with the same directory as in the description, it works.

Duplicate of #17010. This problem was related to 32-bit Linux hosts. Fixed in the most recent 5.1 test builds.
