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

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

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

Can someone please tell me how to Fix it?

Solution 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!

Solution 2:

I have a same problem and I solve it with this :

1. Open Windows Network Connections
2. Right click on VirtualBox Host only adapter that created
3. Choose properties
4. Check "VirtualBox NDIS6 Bridged Networking driver"
5. disable and Enable the adapter

Solution 3:

I had the same issue and this fixed it:

Go to Network and Sharing Center > Change adapter settings and enable these:

• Local Area Connection (if it's disabled)
• VirtualBox Host-Only Network

I think that enabling the second will do the job, but I did the first anyways.

Hope it helps.
