Need some help with android emulator and HAXM issues

I was just wondering if anyone could help me with some android studio issues.. I am not able to run any emulators or debuggable devices on android studio.. It shows the error.."/dev/kvm not found. Enable VT-x in your BIOS security settings, ensure that your Linux distro has working KVM module."
Though I have enabled the VT-x from BIOS settings.. Also, while installing INtel HAXM.. the setup ends prematurely.. though it shows installed afterwards .. But while installing it ends prematurely stating the error "Failed to configure the driver".. It would be great if you could just help me up with this issue!
