Virtualbox is asking for permissions with genymotion & emulator is not starting?

When I am starting genymotion, it is asking for virtualbox permissions(UAC) over and over again. It is okay to do so (if it results in launching the emulator), but this forms a never ending 'permission asking' loop. In the published section it is clearly mentioning "Oracle corporation".
I am using virtual box 2.8.1 and virtualbox 5.1.18 with windows 7.
Thanks,

The reason Genymotion triggers this at startup is that it asks VirtualBox for the list of installed devices. This results in several calls to VBoxManage, an executable provided by VirtualBox. Unfortunately, each time this executable is called you get an UAC.

1.Go to virtual box File-> Host Network Manager
2.It will show available host only networks
3.Remove the ones which are not needed
Happy Coding:)

Genymotion is not working in Windows 10 for Android Emulator

I have tried everything(reinstalled, open as administrator, etc) and it's still not opening the Android 5.x and 6.x emulator.
The error message is :
Unable to start the virtual device.
The virtual device got no IP address.
The VirtualBox DHCP server has not assigned an IP address to the virtual device. To find a solution, please start Virtual Box.
I have followed this tip and this but the error message keeps.
I'm using a Windows 10 Pro.
Any other tip without the need of reinstalling the Windows?

Update:
Hey man I think I caught your problem.
1) Please Open VirtualBox and and Then right click on your Virutal Machine.
2) Select Settings.
3) Open General Setting from the left panel.
4) Open the Basic tab.
5) Choose Linux from the Type option.
6) Then choose Other Linux(64-bit) in the Version Section.
I have tried the option of 32-bit mode in my PC and the same problem happens as you asked in your question. So, select 64-bit mode to make it run.
Note: Android 5.x and 6.x are based on the 64-bit architecture. If you
selected the Other Linux(32-bit) option. Then Virtual Box will try to
emulate a 64-bit program in a 32-bit virtual machine type, which is
not possible.
So, Please make sure that you have selected the Other Linux(64-bit)
option for Android Versions higher than 5.x. (You can run Android
versions upto 4.x in the 32-bit mode.)
Old Answer:
No, You don't need to reinstall windows. It is not an operating system
fault.
I faced this problem.
It is due to the Antivirus Program.
If you have any antivirus program then just disable it and TRY
AGAIN.
You also don't need to set any compatibility mode.
Currently, I am using Genymotion(Version 2.6.0) and
VirtualBox(Version 5.0.12 r104815) in Windows 10 Pro without any error.

how to install genymotion on vmware

Guys I've installed genymotion on virtual box provided with setup . now every time i want to start the virtual device I've to restart my laptop & sometimes even that doesn't help . So I've decided to install that on VMWare 11 . Can anyone help me please on this issue.
If anyone can solve this error which says can't connect to virtualbox ,That would be helpful also. But I still prefer solution with VMWare .
I've tried solution like DHCP server address solution which is suggested by official support site of genymotion , but that doesn't help also.
I've tried glew solution also but their support center doesn't accept log file(text) or image of error.
Snapshot of error :

I had the same issue, Genymotion can't be launched on a virtual machine!
This is quoted from their faq:
Why doesn't Genymotion start from a virtual machine? Genymotion cannot
be run from a virtual machine. Indeed, Genymotion needs a direct
access to the hardware in order to provide OpenGL acceleration.
Running Genymotion from a virtual machine prevents it to directly
access the hardware components. Therefore, Genymotion is incompatible
when installed from VMWare, Parallels, Hyper-V or VirtualPC.

About the problem with virtual box try the following steps:
1. Open Virtual box. Go to preferences.
2. Click on networks option.
3. Click on Host-only networks tab
4. Delete all host adapters.
5. Start Genymotion. It will automatically create a new network adapter with required settings.
The above worked for me.

Genymotion and virtualbox dependency

Why should we install virtualbox when we are using Genymotion, and one thing else, when we are downloading devices in Genymtion, suppose our system crashes, will we get back those devices, that we had already downloaded
any idea

Genymotion works as a virtual machine, therefore requires a virtualization software.
They could make their own software, but that probably seemed to be unpractical and unnecessary, since VirtualBox is good at its job, and is free.
The devices you have already downloaded will be preserved. If your system crashes while it's being downloaded, you'll need to download it again.

Lollipop not start in Genymotion

I have Genymotion 2.3.1 and VirtualBox 4.3.20 installed on Windows 8.1. Other Genymotion devices I have configured (4.2, 4.4) are fine but the Lollipop one will not start.
When I attempt to start it directly from VirtualBox, I get the following errors:
can not find system/bin/install-recovery.sh disabling flash recovery
could not open /sys/class/power_supply/genymotion_fake_path/present
I changed SDK (Android tools directory) manually, but this did not help.

I activated Intel virtualization technology in my bios settings and just update my Genymotion and VirtualBox to Genymotion All in one version.
after a long time wait after genymotion's android Logo, finally The problem solved!
Lollipop not starting from VirtualBox but in genymotion everything is now working fine!

on linux
I have just solved the problem by removing libdrm.so.2 from Genymotion installation dir and rebooting my computer.
If that does not work, you can try to disable GPU open drivers and enable proprietary drivers in System Settings > Software & Updates > Additional Drivers.
Hope this help!

This can also be due to outdated VirtualBox version. Download and install the latest version of VirtualBox.
