I've tried to install KVM in an Ubuntu virtual machine (versions 19.04 and then 16.04) and in both cases I get the same error:

INFO: Your CPU does not support KVM extensions

KVM acceleration can NOT be used

I can use QEMU but it's slow and I need KVM in order to install particular software. I'm using VMWare Workstation Pro.

Are there any settings I need to modify to be able to do it?

  • thanks @Odecif but in that post, the user tried to install it on a Virtual Box VM, while I'm using Ubuntu

  • Most often you need to enable KVM somewhere in the bios. Details are unfortunately very manufacturer specific.

    @ChristianEhrhardt but how can I do that from vmware workstation? Because my Ubuntu is a virtual machine, so I want to install a virtual machine inside a virtual machine :)

I managed to do it by editing the setting of my Ubuntu virtual machine in VMWare Workstation: I edited the Processor section and enabled the option Virtualize Intel VT-x/EPT or AMD-V/RVI under Virtualization Engine.
