[android] 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

Screenshot:

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

Can someone please tell me how to Fix it?

I recently had this problem, and setting up the virtual network configurations did not work. I found this then: https://forums.virtualbox.org/viewtopic.php?f=6&t=70199

Virtualbox seems to vhave a bug in recent releases. Reinstall it using cmd prompt, and use this as arguments for the executable : -msiparams NETWORKTYPE=NDIS5

This did the trick to me. I'm on windows 10, using the VirtualBox-5.0.10-104061-Win version.
Note that, this seems not to be a problem with genymotion only. Hope I spare you some time. I sure spent more than I thought it would take me.

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!

I had the same problem in Mac OS, it was a bug in VirtualBox V5.0.2 and fixed in V5.0.3, I installed V5.0.3 and no more problem

In Win10 it might be helpful to download VirtualBox latest version.

It was the only thing that solved it for me. Hope it will save someone some time and trouble.

In Mac, Open Oracle Virtual Box and Goto VirtualBox -> Preferences -> Network. Select the tab'Host Only Networks' & delete vboxnet0. It will be recreated next time you launch genymotion emulator.

It may be because of you assigned more than 50 % RAM memory to your emulator.

Open Oracle VM --> Settings --> General And then Decrease memory assigned to the device.

And in Newer Versions, Open Oracle VM --> Settings --> System --> MotherBoard Tab And then Decrease memory assigned to the device

Just download and install the latest version of Virtual box, run it then run the emulator and viola, it will be up and running. This one worked for me.

Open Virtual Box. Select your virtual Android Device and click on Settings.

Select Network.

Make sure "Enable Network Adapter" box is checked. Also Make sure "Attached to:" has "Host-only Adapter selected". Note the name of the adapter.

Open Settings and click on "Network & Internet"

In the window that opens click on "Change Adapter Options"

In the window that opens you can find many Network names listed. Find the network name that matches with the network name that you noted earlier in the Virtual Box.

Note if that network is Enabled or Disabled.

If the network is Disabled, right click and click Enable.

If the network is Enabled, right click, click Disable and then again click Enable.

Close the window, open Genymotion and start your Virtual Device. The device should now boot without any error.

You can check the version of your genymotion and virtualbox. The genymotion 2.5.3 would work better with virtualbox 4.3.30.

Just download latest Virtualbox version. Is works for me.

I had the same issue and figured it out today. I had to release the existing virtual drives before Genymotion would allow me to create a NEW virtual drive. Once you click create new drive, it prompts you to login to your Genymotion cloud account. Now I am actually able to run it. Hope this helps.

Edit* Also tried reinstalling AND repairing Virtualbox multiple times and still got same error. Only until I released the existing virtual drives did it start working.

after 2 days searching in web, i found it's related to issue with the new NDIS6 driver, so you can install it to use the old NDIS5 driver

Try installing Old Version of Virtual Box (run as administrator)

VirtualBox-5.x.x

VirtualBox 5.2.6 worked for me Windows 10 , Genymotion 3.0.3

There is a known issue with the new NDIS6 driver, you can install it to use the old NDIS5 driver

Steps I followed:

1.Uninstall Virtualbox and try reinstalling it using command prompt.
2. Run command Prompt in administrative mode;
3.Check your Network Drivers if you are using NDIS6 or 6.+ ;
  Write >VirtualBox-5.0.11-104101-Win.exe -msiparams NETWORKTYPE=NDIS5;
4.Now Follow the install steps and finish installation steps.
5. Now try starting device with VirtualBox.

This worked for me.

Select yourVM -> Settings -> Network -> Disable the Network Adapter (It will be re-configured by Genymotion)

Start the Android Image again in Genymotion UI (not in Virtualbox), It should work now!

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.

in my case there was 2 reasons (checked) that my genymotion device couldn't run on windows 10/64bit

1. VPN was running and connected

2. amount of "base memory" :

run virtual box > choose your device in the list > Settings > System (left list) > set your base memory on 1024

It seems your VirtualBox installation doesn't work correctly. You should try to reinstall/upgrade VirtualBox so that during the installation process it fixes this "Interface not found" issue.

1.Run VirtualBox as administrator

2.Go to File -> Preferences -> Network -> Host Only Networks

3.Add a new one or just edit and delete all existed

Adapter Tab:
        IPv4 Address:        192.168.0.201
        IPv4 Network Mask:   255.255.255.0
    DHCP Server Tab:
        Server Address:      192.168.0.100
        Server Mask:         255.255.255.0
        Lower Address Bound: 192.168.0.101
        Upper Address Bound: 192.168.0.199

At fast open VirtualBox and then open Genymotion. It then not work just change the Address and try again and restart your PC.

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

Try this one. it works for me. :)

I also disabled Hyper-V to makes mine work.

Genymotion FAQ

To date, VirtualBox is not yet fully compatible with Windows 10. As Genymotion relies on the use of VirtualBox in the background, some problems may arise. If you have any troubles running Genymotion on Windows 10, we first recommend that you put VirtualBox in a clean state. To do so:

1. Uninstall VirtualBox.Reboot your computer if prompted by the installer.
2. Install the version of VirtualBox recommended for Windows 10 Reboot your computer if prompted by the installer.
3. Open VirtualBox and go to File > Preferences > Network.
4. Remove all existing host-only networks by clicking Description 1.
5. Start Genymotion a first time.
6. In the event of a failure, start Genymotion a second time.

If Genymotion still doesn’t run, you can manually configure a host-only network:

1. Open VirtualBox and go to File > Preferences > Network.
2. Add a new host-only network by clicking Description 1.
3. Edit its configuration by clicking Description 1.
4. In the Adapter tab, set the following values: IPv4 Address: 192.168.56.1 IPv4 Network Mask: 255.255.255.0
5. In the DHCP Server tab, set the following values: Check Enable Server. Server Address: 192.168.56.100 Server Mask: 255.255.255.0 Lower Address Bound: 192.168.56.101 Upper Address Bound: 192.168.56.254

I did the following to resolve mine:

1. Open VirtualBox and check the new machine that is created for you by GenyMotion
2. Right Click on it and choose Settings then go to the Network section/tab

3. In Adapter 1 tab, It should be attached to Host-Only Adapter. Check what is the name of the used adapter Name then close it.

4. Open File|Preferences in Virtualbox, then go to Network section/tab

5. Under Host-only Networks tab, find the same name you have already gotten in step 3.

6. Double click on that name and apple the following configuration

   • Adapter Tab:
   • IPv4 Adapter: 192.168.65.1

   • IPV4 Network Mask: 255.255.255.0

   • DHCP Server:

   • Check "Enable Server"
   • Server Address: 192.168.65.100
   • Server Mask: 255.255.255.0
   • Lower Address Bound: 192.168.65.101
   • Higher Address Bound: 192.168.65.255

The following resolved the problem for me:

1. Go to Control Panel -> Network and Internet -> change adapter settings
   Right click on VirtualBox Host-Only Network and select properties The following options must be ticked

   • client for microsoft networks
   • virtualBox bridged network driver
   • qos pocket scheduler
   • file and printer sharing for microsoft network

   If see another program select and uninstall it.

2. In VirtualBox go to File -> Preferences -> Network
   Double click on VirtualBox Host-Only ethernet adapter
   Edit like this:
   IPV4 address: 192.168.56.1 mask: 255.255.255.0
   DHCP: address 192.168.56.100 mask: 255.255.255.0
   low bounds: 192.168.56.101 high bound: 192.168.56.254
   Restart or log off your windows and start genymotion
   If that didn't solve your problem in VirtualBox go to File -> Preferences -> Network and delete Host-Only ethernet adapter.

As it mentioned above assigning more than 50 % RAM memory to your emmulator.

For me fixed this way too.

My machine have 8GB and I assigned 4GB for per device. Resetting it solve my problem.
