How can KVM be located by Android Studio on Ubuntu 14.04 LTS

See the instructions here: https://help.ubuntu.com/community/KVM/Installation

In short:

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils
sudo adduser `id -un` libvirtd
sudo adduser `id -un` kvm

Then log out and back in again, and check that it is working by running:

virsh -c qemu:///system list

Some more instructions from Intel: https://software.intel.com/en-us/blogs/2012/03/12/how-to-start-intel-hardware-assisted-virtualization-hypervisor-on-linux-to-speed-up-intel-android-x86-emulator

I had exactly the same problem. I managed to fix it after minimal fuss by enabling virtual technology in the BIOS settings. It may be a slightly different method for different computers but on my HP Pavillion Laptop you simply press F10 at start up to get the BIOS options. Then find the tab which allows you to set VT to enabled. As soon as this is done (assuming you have kvm), it works. Just restart and run in terminal.

kvm-ok

I had the same problem and it was because of the modprobe:

whk @ whk-MS-7817: ~ $ sudo kvm-ok
[sudo] password for whk:
INFO: / dev / kvm does not exist
HINT: sudo modprobe kvm_intel
modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep () moddep could not open file '/lib/modules/3.13.0-43-generic/modules.dep.bin'

I found the same error message here:https://dainaccio.wordpress.com/2014/12/19/how-to-solve-wifi-not-working-in-a-fresh-installed-linux-mint-17-sony-vaio-atheros-ath9k/

I checked the version of my kernel:

whk @ whk-MS-7817: ~ $ uname -mrs
3.13.0-43-generic Linux x86_64

It was the same version of the post so talves was a bug, so I proceeded to repair:

sudo apt-get install --reinstall linux-image-3.13.0-43

And presto!

whk @ whk-MS-7817: ~ $ sudo kvm-ok
INFO: / dev / kvm does not exist
HINT: sudo modprobe kvm_intel
INFO: Your CPU Supports KVM extensions
KVM acceleration can be used

Now reboot and working properly. Tested in Android Studio 1.0.2 and Ubuntu 14.04 LTS
