ERROR: x86 emulation currently requires hardware acceleration!

Ketika Anda menjalankan perintah :

cordova emulate android

Anda mendapatkan pesan error :

Running command: /CordovaApps/openthinksas/platforms/android/cordova/run --emulator

WARNING : no emulator specified, defaulting to Nexus_5_API_21_x86

Waiting for emulator...

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).

Coba cek, apakah CPU kita mendukung acceleration atau tidak, di ubuntu, untuk memeriksanya jalankan perintah :

sudo kvm-ok

Kalau outputnya seperti ini :

INFO: Your CPU does not support KVM extensions

KVM acceleration can NOT be used

Sepertinya harus mengganti PC/Laptop yang Anda gunakan .... :(

Jika perintah kvm-ok tidak dikenali, install dulu paket yang menyertakan perintah ini :

sudo apt-get install cpu-checker
