After you have updated the latest GenyMotion Version to 2 10 from 2 02      Open GenyMotion Go to the List of your 2 02 Devices Left click the item and then right click on the menu to   Delete all your 2 02 Virtual Devices Click the Add button at the top to add a New Device  Log into your account Select the device you want  You can only select one device at a time Click the Next button  Notice the Version number says - 2 10  There is other info about the device here  Your device will start downloading to your GenyMotion Folder on the Drive   C  8  After you download it  double click it to open up the Virtual Device like you normally would  Repeat for other device you want      C   Users  AppData Local Genymobile Genymotion deployed

Update  Before you read further  I want to notice that I didn t have any problems since I upgraded VirtualBox to 4 3 4   I use VirtualBox 4 3 2 under Ubuntu 13 10  I had same issue after upgrading from Genymotion 2 0 0 to 2 0 1   These are the steps I followed to fix this  although I m not sure which one works for you   Step 1  Start VirtualBox  go to menu File Preferences menu  go to Network section  select Host-only Networks tab    If you don t have any adapter defined  then you can create one  as indicated below  or you can ignore step 1 and Genymotion will create it when you try to start the VM   If you do have an adapter there  vboxnet0  click the edit button  In the edit window  you must have DHCP server enabled AND the IP address and allocation pool of the server must be inside same network as the IP of the network controller  For example  I use     IPv4 address netmask  192 168 56 1 255 255 255 0  on Adapter tab  DHCP server enabled checked  on DHCP server tab  Server address netmask  192 168 56 100 255 255 255 0  Server lower upper address  192 168 56 100 192 168 56 254   Still in VirtualBox  select the Android VM you have  click Settings button  select Network section  In the Adapter 1 tab  you should have    Enable network adapter checked Attached to  Host-only adapter Name  vboxnet0   Normally  if you have all these settings  it should work ok  but it didn t for me  So I moved to step 2   Step 2  As indicated by Genymotion  start VirtualBox  go to menu File Preferences menu  go to Network section  select Host-only Networks tab and delete the defined adapters   Start your VM in Genymotion  Genymotion will recreate the adapter with proper settings  as described in step 1   Normally  if step 1 didn t work for you  step 2 should work ok  but it didn t for me  So I moved to step 3   Step 3  Delete and recreate the Android VM in Genymotion  VirtualBox host-only network settings I left as described in step 1    This solved my issue and Android VM works ok now  Good luck   Andrei   Update  A day after posting answer  when I was first starting a VM in genymotion  it gave again same error again and vboxnetdhcp process crashed  and restarted   On second and later start attempts it worked ok  So it might still be some minor issue there with VirtualBox DHCP process   Update  The issue seems to reside in virtual Box DHCP server which crashes    usr lib virtualbox VBoxNetDHCP --network HostInterfaceNetworking-vboxnet0 --trunk-type netflt --trunk-name vboxnet0 --mac-address 08 00 27 72 4C 7B --ip-address 192 168 56 100 --netmask 255 255 255 0 --verbose Floating point exception  core dumped    Deleting and recreating the VM fixed again the issue  Maybe Genymotion sends some invalid data to VBox DHCP that makes it crash  still a VBox bug though

For VIrtual Box 5 x - the settings from above comments are set automatically  Now for the error    1 Make sure that you have enough Processor s  and Base Memory - so the PC can support VM configuration I use 1 procesor and 1024MB for all VM s   2 Delete any unused VM from Genymotion and Oracle VirtualBox Manager - seems to reserve their configuration  though you use it or not that specific  VM

For windows users    Disable Hyper-V and its tools  If you are a windows user  the problem might simply be because of having multiple virtualization technologies in your system   You might be having Hyper-V and its related features enabled  Just simply turning them off and rebooting your system can do you help sometimes     Here is how you do it    Fire up Run  Ctrl R  Type appwiz cpl and press enter Head over to Turn Windows features on or off Find Hyper-V and deselect everything under it  Press Ok and give your system a restart    Fireup your genymotion and check to see if it works again  If there is an error prompt saying something like DHCP cant assign IP    just try restarting your genymotion application

In my case  the only option was to remove the VM and download it again  No re-configuration of the host-only adapter did not help  I used different addressing of DHCP  Virtual Box I updated to version 4 3 4 and Genymotion to 2 0 2

If all the other answers here fail  you can check that you have a correctly created host-only network in VirtualBox  which is basically what other answers here come down to    https   stackoverflow com a 33733454 586754  with screenshot  worked for me   Basically  go to Windows network adapter settings for the  VirtualBox Host-Only Ethernet Adapter  and check  VirtualBox NDIS6 Bridged Networking Driver    This made both Genymotion and Xamarin Android Player work again

I had the same problem and tired all the above solutions and did not work for me  the problem was because multiple networks make conflict between VMware and VirtualBox  and other VPN connections  The solution i followed is    solution 1     uninstall virtualbox and reinstall the last update of it   solution 2     If solution 1 not working  try this uninstalling all VPN programs  VirtualBox  Genymotion and reinstalled VirtualBox and Genymotion again  both solutions worked with me

If as me you ve tried everything above  especially windows 10 users   and nothing helped here is what eventually solved the issue  The solution was ridiculously easy but took a day to figure it out    Recommended to remove host only network adapter from virtual box  to do that open virtual box File- Preferences- Network- select tab host only network adapter- remove all  no worries when you start a vm from genymotion it will create new   Now open Genymotion and try to start your virtual device  Get the error   that s good follow second step  What actually fixed the issue  Go to Control Panel- Network and Internet- Network Connections  on there you should see an Ethernet network adapter that virtual box created   it was created automatically when you started device from genymotion   so right click on it then Properties then CHECK VirtualBox NDIS6 Bridged Networking Driver  see image attached   You re done  Start your device from genymotion  should work now

I know this post is old  but in case someone is searching google i think i should mention what fixed my problem  After the 3 steps from above the error message was gone but the screen still stayed black and opening an  apk got stuck on file transfer  It had something to do with a VPN application  in my case Hamachi   I just closed it and then the emulator ran fine  This post prompted me to do so  https   groups google com forum   searchin genymotion-users network genymotion-users QAX UrAzEn0 o947IXpsDuIJ
