Nested KVM virtualization

[Soluce-Technologies]

Operating system

Ubuntu 24.04

Description

I have this warning :

Warning: Nested KVM virtualization detected, this might cause issues running macOS!

The service start well, but then during the installation process after 1 min machine crash, mac os restart. I am unable to complete the installation.

Any idea ?

I've the same warning but I'm running it on a virtualized host already so it's kind of expected. Are you running the container on bare metal?

Have you enabled svm (amd)/vmx (intel)? check: lscpu | grep Flags

[RambokDev]

It's working well on a bare metal instance.

[kroese]

It's not adviceable to run the container inside a VM, but only on bare metal. Because it will introduce all kinds of weird issues, and thats why I print the warning in the log file when it detects such a setup.

@Soluce-Technologies how did you install docker on your ubuntu machine?
You would have to install the docker engine NOT Docker Desktop.
"Docker Desktop on Linux runs a Virtual Machine (VM) ..." (https://docs.docker.com/desktop/setup/install/linux/)

To install docker engine:
https://docs.docker.com/engine/install/ubuntu/

to solve that you add to you yml :
devices:
- /dev/kvm:/dev/kvm
- /dev/net/tun
privileged: true

privilege is needed
