I just installed Debian 12, downloaded Android Studio and was following this article to enable VM acceleration: https://developer.android.com/studio/run/emulator-acceleration?utm_source=android-studio&hl=pt-br#vm-linux which says:

To use VM acceleration on Linux, your computer must also meet these requirements:

  • For Intel processors: Support for Virtualization Technology (VT-x), Intel EM64T (Intel 64) features, and Execute Disable (XD) Bit functionality enabled.

I have an Intel Core i3 10100 and the specifications here https://www.intel.com/content/www/us/en/products/sku/199283/intel-core-i310100-processor-6m-cache-up-to-4-30-ghz/specifications.html say:

  • Intel® 64: Yes
  • Execute Disable Bit: Yes
  • Intel® Virtualization Technology (VT-x): Yes
  • Intel® Virtualization Technology for Directed I/O (VT-d): Yes
  • Intel® VT-x with Extended Page Tables (EPT): Yes

But when I run

egrep -c '(vmx|svm)' /proc/cpuinfo

I get 0 as response.

And when I run

sudo kvm-ok

I get:

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

I already enabled VT-d on the UEFI, I don't know what else to do.

  • Even if the CPU has it, you typically have to enable the virtualization options in the BIOS.

  • @acejavelin sorry, I'm so dumb, I just restarted my pc after posting this to fiddle around on the UEFI and found it, the VT-x was disabled

  • This suggests you need to enable VT-x within the BIOS.

Even if the CPU has it, you typically have to enable the virtualization options in the BIOS.

Reboot the PC and enter the BIOS/UEFI firmware setup and check the CPU or Advanced settings, the exact location varies by firmware and manufacturer, but verify VT-x is enabled. This is sometimes just referred to as Intel Virtualization Technology, Virtualization Technology, VT-x, or SVM, depending on the BIOS/UEFI firmware.
