I'm trying to enable virtualization for genymotion on my Acer aspire e1-531. It doesn't have the advance option in bios and all solutions I've seen are for Windows 🥺

According to your lscpu output:

... VMX unsupported

and official information from Intel web-site your Pentium B960 does not support Intel® Virtualization Technology (VT-x).

So you can use only software virtualization in VirtualBox which is really slow.

  • Unfortunately Intel cripples functionality on their cheapest CPUs, not just performance. :/ Definitely something to keep in mind when shopping for anything lower-end than an i3, i.e. Pentium/Celeron. e.g. before Ice Lake, when the mainstream CPUs have AVX2, the budget CPUs are only half width and don't support AVX or even BMI1/2. (e.g. Comet Lake Pentium G6405 launched Q1 2021 in that sorry state: intel.ca/content/www/ca/en/products/sku/201901/…). Fortunately Intel isn't the only budget x86 vendor... Jul 25 at 20:56
