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

so I can use QEMU but it's slow and I need KVM in order to install a software. I'm using VMWare Workstation Pro. Is there any settings I need to modify to be able to do it?

  • It seems that you are experiencing this issue askubuntu.com/questions/328748/…. – Odecif Sep 11 at 15:26
  • thanks @Odecif but in that post, the user tried to install it on a Virtual Box VM, while I'm using Ubuntu – itd Sep 11 at 21:15
  • Most often you need to enable KVM somewhere in the bios. Details are unfortunately very manufacturer specific. – Christian Ehrhardt Sep 12 at 6:55
  • @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 :) – itd Sep 12 at 9:44
  • Ah that would be communities.vmware.com/docs/DOC-8970 then. – Christian Ehrhardt Sep 12 at 14:57

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