VirtualBox installation / start-up¶
Downloading over an unstable network¶
If your network connection is unstable or very slow and you are unable to download the Quantum Mobile image in one go, consider using a download manager that can resume downloads, such as the
wget command line utilities.
Importing the VM results in an error:
This may indicate that your hard disk is full. Do you have enough disk space to accommodate both the Quantum Mobile image and the extracted image (sizes reported in the installation instructions of the release?
Running the VM yields an error:
VMDK: Compressed image is corrupted¶
Your image file is corrupted - try downloading it again.
You can verify the integrity of the image by computing its md5 hash (
md5sum <filename>) and comparing the result to the hash provided on the release page.
Running the VM yields:
VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)¶
Enable Virtualization Technology (VTx) and Virtualization Technology Directed I/O (VTd) in your BIOS.
I start the Quantum Mobile, but I only get a black screen¶
You probably have VirtualBox version 5. You need VirtualBox 6.x to run Quantum Mobile. Upgrade your VirtualBox and try again.
Running the VM used to work fine, but recently you start getting errors
The VirtualBox kernel modules do not match this version of VirtualBox. Executing ‘/sbin/vboxconfig’ may correct this.
The kernel of your host OS may have been updated since the installation of VirtualBox. Follow the instructions above in order to recompile the VirtualBox kernel extensions.
On Ubuntu hosts, you get an error:
Kernel driver not installed¶
Stackoverflow has some help on this.

IMPORTANT Preliminary tests indicate that VirtualBox 6.1 (released Dec 10th, 2019) addresses at least one of the long-standing graphics issues. Please upgrade.
On macOS hosts, the content of the VirtualBox window stays in place when dragging it using the window bar¶
Minimize the window and maximize it again.
On VirtualBox 6, graphics becomes super slow after a few minutes¶
