原文网址：http://askubuntu.com/questions/564910/kvm-is-not-installed-on-this-machine-dev-kvm-is-missing

I‘m using Ubuntu 14.04 ...recently install the android studio I run a hello world program there will be a error:

/home/praveen/Android/Sdk/tools/emulator -avd Nexus_6_API_21 -netspeed full -netdelay none
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure KVM is properly installed and usable.
CPU acceleration status: KVM is not installed on this machine (/dev/kvm is missing).

Use the below command to check whether the KVM is installed in the machine or not,

kvm-ok 

Output:

INFO: /dev/kvm exists
KVM acceleration can be used

Output like the below means,

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

In this scenario need to install KVM using the below command,

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils

Hope this helps.

Worked on Ubuntu 15.04, Intel‘s CPU

1. sudo apt-get install qemu-kvm
2. Enable Virtualization Technology in BIOS
3. sudo kvm-ok

2. Android studio 中文社区
