When I try to run android emulator I got following error and my emulator doesn't start at all.
Error:
Please check if you can update your video driver.
If it doesn't help, try to Edit the AVD and set "hw.gpu.mode=off".
When I set hw.gpu.mode=off then emulator starts but it super extremely slow even if I add 4GB of ram. I think it's due to hw.gpu.mode=off. Is there any other workaround still to use gpu?
Componenets which are enabled:
Hyper-V
Virtual Machine platform
Windows Hypervisor Platform
Virtualization enabled in BIOS
Besides I've tried different fixes available on internet like : disabling enabling Hyper-V & Windows Hypervisor platform including system restarts etc but none seems to work yet.
There is an error when I use command 'systemctl' in centos in Termux.
The error goes like this
By the way, Termux is an Android terminal emulator and Linux environment app that works directly with no rooting or setup required.
Successfully install Genymotion, and run the Virtual Device.

As we know that Genymotion is using VirtualBox for its virtualization engine. The Virtual Device in Genymotion also appears in VirtualBox Manager. But when i trying to run that Virtual Device through the VirtualBox Manager, i got this error.

So whats wrong with that? Can I run the Virtual Device in VirtualBox instead of Genymotion?
There is nothing wrong: Genymotion virtual devices should not be run from VirtualBox. Use Genymotion to launch your devices.
Since i started developping applications using Rad Studio 10 i'm able to test the windows and android versions on my desktop.
However, i do not have a Mac. So i decide to create a virtualbox guest Mac OSX Sierra on my Windows 10 Pro 64-bit. It works fine but i'm not able to connect and share files between Mac/Windows or test iPhone using Rad Studio.
What steps do it requires to configure my virtualbox to work with RAD Studio 10 ?
You are lucky if virtual box work fine, me i always have trouble with it (especially connecting the ios device). However i found that vmware is much more stable, full screen resolution, much (much) better to handle the iphone connection via usb, and i didn't have yet any crash when on virtual box it's quite often
on vmware, you can also copy/past text from the virtual machine to the host that is very usefull when debuging (on virtual box you can not)
on both (vmware and virtual box) you need to setup the connection as bridged connection. after you successful installed the emb pa server, you can get the ip of the machine with the command "i"
Whenever I have Virtualbox running, I cannot start an Android emulator image (and vice versa). The error message in the AVD manager is
ioctl(KVM_CREATE_VM) failed: Device or resource busy
ko:failed to initialize KVM
How can I make both run at the same time?
That is a Ubuntu 64 bit, all involved software is of the latest released version.
Removing the kvm kernel modules (using 'sudo rmmod kvm_intel kvm') makes it possible to run the Virtualbox and the Android emulator at the same time but the performance of the Android emulator in such a setup is extremely bad. If possible it is better to shutdown the Virtualbox emulator and unload its driver (vboxdrv) by running 'sudo /etc/init.d/vboxdrv stop'. Google suggests this "solution" on its Android Emulator page in the section about Linux.
I got the same VirtualBox conflict.
Solved it by using ABI different from "x86" (armeabi-v7a in my case)
I stopped the virtual machines I had running with VirtualBox. This made the error disappear.
I had the same problem on Ubuntu 13.10.
Try to remove kvm and kvm_intel kernel modules.
To do this:
Stop all emulators.
Run command: 'sudo rmmod kvm_intel kvm'
Without these kernel modules Virtualbox and Android emulators can work at the same time.
BTW, I do not know why the modules are loaded.
There is finally a fix for this.
Follow these steps for macOS:
In Android Studio Go to Tools -> Android -> SDK Manager
Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .
Go to the extras directory of the Android SDK location displayed in the preferences. On MacOS you can do this:
open ~/Library/Android/sdk/extras
Install the HAXM packing by opening IntelHAXM_6.1.1.dmg, then opening IntelHAXM_6.1.1.mpkg in the mounted folder, and following the installer instructions.
Follow these steps for Windows:
In Android Studio Go to Tools -> Android -> SDK Manager
Confirm you have the latest version of Intel Emulator Accelerator HAXM installed (v6.1.1) .
Go to the extras directory of the Android SDK location displayed in the preferences. Something like:
C:\Users\<username>\AppData\Local\Android\sdk\extras
In that directory is some kind of file like intelhaxm-android.exe. Run it.
You also can change CPT/ABI setting from x86 to arm in emulator settings.
I finally made this problem obsolete by using Genymotion instead of the standard Android emulator. Besides not having this conflict, it is several times faster than the normal emulator.
Another solution is to use libvirt backed vagrant using vagrant-libvirt plugin.
For those who are developing on Linux and are stuck with a host of back-end systems running inside virtualbox, a simple solution is simply to create a virtualbox X86 Android VM and expose the 5555 port on the NAT interface tunnelled from localhost through PAT.
No need for slow arm AVD, no need for libvirt/vagrant let alone killing kvm!
Then let adb know about it
$ adb tcpip 5555
restarting in TCP mode port: 5555
$ adb connect 127.0.0.1
connected to 127.0.0.1:5555
$ adb devices
List of devices attached adb server
* daemon started successfully
emulator-5554 device
Then, pressing run or debug, in Android Studio will deploy and execute on that VM.
You have complete control under Android Studio debugger.
Though it's a workaround either, but definitely better than disabling KVM as everyone suggesting.
Just run the virtualbox guest in KVM instead. For example (kvm here is just a script running a qemu-system-x86_64 -enable-kvm):
kvm Win7.vdi -boot c -m 2G -vga qxl
In some cases, we need to keep virtualbox machines up and running therefore let all the virtualbox machines keep running, switch to physical mobile device to test your application instead of emulator.
you can use expo if you are doing with react-native or your real android/ios device.
I resolved it by installing HAXM 6.1.2.

This might be out of topic, due to the fact that OP requested VirtualBox + KVM in the same time, but still, it might be the workaround:
I was looking for a way to launch Windows 7 and AVD on Ubuntu 18.10 x64. Turning off KVM is not an option due to the fact that performance of AVD is critical to me. I have installed Windows 7 via Virtual Machine Manager (virt-manager package) and now both the AVD and Windows 7 are hardware accelerated.
Here is how solved this issue, using vagrant and it's two plugins 'libvirt' and 'mutate':
Open terminal and set environment variables:
export VAGRANT_DEFAULT_PROVIDER=libvirt
export VAGRANT_HOME=/home/directoryToStoreVagrant/
VBoxManage list vms
Now copy the a the code obtained from last command like
"c1530713-aec2-4415-a6b5-b057928c7e5f" and use in the following:
vagrant package --base c1530713-aec2-4415-a6b5-b057928c7e5f
--output window7.box
vagrant init window7
vagrant up window7 --provider=libvirt
vagrant box list
You need to install some vagrant plugins like libvirt and
mutate. Mutate will convert .box to libvirt VM:
vagrant plugin install vagrant-libvirt
vagrant plugin install vagrant-mutate
Converting vagrant box to libvirt:
vagrant mutate window7_.box libvirt
Now you can initialise the vagrant VM. If any error persist move to
edit your Vagrant file. Like for me I uncomment the line starts with
config.vm.network and then run command below:
vagrant up --provider=libvirt
This is how I was able get rid of this error completely
