Unable to start emulator device in ubuntu

Issue

I got an error that avd device cannot launch. I have solution on this link, but cannot solve my problem. I though It may conflict with my genymotion, so I use command killall virtualbox. It said

virtualbox: no process found.

I use ubuntu 14.04 LTS and I use android studio v2.2.

I know it should not be ask, but I have no solution. Please help.

Here the message:

Solution

This is mostly because you have either VirtualBox or VMware running on the same machine. The reason (at least that’s what I think) is that the kernel module of VirtualBox or VMware and KVM can’t take Advantage of Intel VT-x or AMD-V at the same time.

So Restart your system once. It should work
