Cannot launch Android emulator on ec2 instance

hi I’m trying to launch an Android Emulator on Amazon EC2 instance(ubuntu).

Steps I had followed:

1) Installed ubuntu-desktop on ec2 instance.

2) installed and configured vncserver in ec2 instance.

3) can able to view remote desktop of my instance on my local machine browser using realvnc.

But when I tried to launch emulator from command line like

./emulator -avd myemu

it throws the following error

libGL error: failed to load driver: swrast

I guess the problem is with some graphic drivers.

How can I solve this.
