android - Unable to start Genymotion Virtual Device - Virtualbox Host Only Ethernet Adapter Failed to start

Question

I'm using Genymotion v13.0 on Windows 8 Pro to create Virtual Device successfully, but when I try to run it I get this error: Unable to start Genymotion Virtual Device.

Screenshot:

Trying to run it via Virtualbox, I got this error message: Virtualbox Host Only Ethernet Adapter Failed to start

Screenshot:

Virtual Device previously could run well until I got this issue.

Can someone please tell me how to Fix it?

Answer 1

This worked for me using GenyMotion 2.0.3 and VirtualBox 4.3.6. My problem was I have an existing host-only adaptor that is used by Vagrant. I can't simply delete it, it will trash my Vagrant VM.

Create a new host-only adaptor in the Virtual Box global settings.
Give it a separate address space from any existing host-only adaptors. For example, I set mine up as follows, where I also have a vboxnet0 (used by Vagrant) that uses 192.168.56.x

name: vboxnet1
IPV4 address: 192.168.57.1
mask: 255.255.255.0

DHCP:
address 192.168.57.100 mask: 255.255.255.0 low bounds: 192.168.57.101 high bound: 192.168.57.254

Then, edit your existing GenyMotion VM to use this host-only adaptor, and restart it from GenyMotion.

Good luck!
