Linux - An error has occurred while trying to create a virtualbox host-only network interface

This error can have several different causes. Here are the main known cause and possible solutions:

1. You are trying to run Genymotion Desktop in a virtual machine, a server or a Cloud instance (AWS, GCP, Azure, ...)

Genymotion Desktop has been designed to run in a physical environment, not in a virtual machine or a server. For this reason, Genymotion Desktop will not work if run in Linux VMs, Linux servers and Linux Cloud instances.

For more details, please refer to the following articles:

• Can Genymotion Desktop run in a virtual machine?
• Can Genymotion Desktop run on a server?
• Can Genymotion Desktop run in a Cloud service (AWS, Google Cloud, MS Azure, Alibaba, etc.)?

2. You are using a VPN and/or a restrictive firewall

VPN clients and restrictive firewalls may interfere with VirtualBox and Genymotion Desktop.

For more details, please refer to the following articles:

• Genymotion Desktop and VPN
• Genymotion Desktop and firewalls

3. VirtualBox has been freshly installed

If you have just installed VirtualBox, it is recommended to reboot your PC.

4. vboxdrv kernel module is not installed

1. Make sure that the dkms package is installed and that it compiles VirtualBox kernel modules each time a new kernel update is available. To do so, run:

   modinfo vboxdrv

   If the vboxdrv kernel module is loaded, it should return (version numbers may differ):
   

   filename: /lib/modules/5.11.0-40-generic/updates/dkms/vboxdrv.ko
   version: 6.1.26_Ubuntu r145957 (0x00300000)
   license: GPL
   description: Oracle VM VirtualBox Support Driver
   author: Oracle Corporation

   If not, try to reload vboxdrv kernel module manually:
   

   sudo modprobe vboxdrv

   If this doesn’t work, rebuild VirtualBox kernel modules:
   
   Ubuntu/Debian
   

   sudo apt-get --reinstall install virtualbox-dkms

   Fedora

   sudo /sbin/vboxconfig

2. Reboot your system

For more information, please refer to VirtualBox documentation. If this doesn't help, try to remove VirtualBox altogether and re-install it.

5. No host-only interface is accessible

This happens in some rare cases, for example when VirtualBox has been updated from a version 6.0.X or 5.X.X.

To fix this:

1. Open VirtualBox
2. Go to File > Host Network Manager...
3. Remove all the host-only interface (vboxnet0, vboxnet1, etc.):
   
4. Close VirtualBox
5. Launch Genymotion Desktop
