Your CPU does not support KVM extensions

[tong123123 (Kei Kei)]

I install ubuntu 22.04 on vmware player, then follow the procedure in
https://docs.docker.com/desktop/setup/install/linux/ubuntu/
section [Install Docker Desktop]
then when start docker desktop, error “KMS is not enabled on host…” is shown, then I follow the link, and type

sudo modprobe kvm
sudo modprobe kvm_intel
sudo kvm-ok

and it returns error

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

I checked cpuinfo by

less cpuinfo|grep vmx
less cpuinfo|grep svm

both nothing return…Does this mean my cpu cannot use docker desktop for linux?
But I check intel website, my cpu is 11th Gen Intel(R) Core™ i5-1135G7 @ 2.40GHz 2.42 GHz and should support Intel® Virtualization Technology (VT-x) .

What can I do now?
Then I can just use docker engine without GUI?

Solved finally. In VMWare player, select the VM, choose VM, edit VM setting, then choose processor, in Virtualization engine, check the checkbox "Virtualize Intel VT-X/EPT or AMD-V/RVI.

Can you share the os you run the VMware player (btw. Workstation Pro is free for personal use)?

I am asking, because nested virtualization won’t work on Windows if any Hyper-V component is enabled. For instance, enabling the WSL feature will install Hyper-V components.

run VMPlayer workstation on Windows 11, install ubuntu on VMPlayer, then install Docker for linux on ubuntu.

In my host Windows 11, if I type
wsl -l -v
it returns

  NAME      STATE           VERSION
* Ubuntu    Stopped         2

and in “Turn Wndows features on or off”, the checkbox “Heper-V” is unchecked.
So my host Windows 11 Hyper-V component is NOT enabled?

[meyay (Metin Y.)]

Well, if the WSL feature is enabled then a minimal set of hyper-v components is installed.
I am surprised that nested virtualization worked in that scenario.
