VM's wont install

Post by sThorn »

Hello,
I'v been trying to install defferent VM's on my VirtualBox (Version 6.1.12 r139181 (Qt5.6.2)).

I'v used VirtualBox earlier in the past on another host with no problem, now the installer never seems to finnish.
On fedora i get this error:

Code: Select all

The following was filed automatically by anaconda:

I'v tried Ubuntu but the error i get there does not show as much.
I was not able to find any relative information about this.
I can run Docker on the same machine with no problem, I dont have Docker and VirtualBox running at the same time.

I have all logs from the fedora-install saved:

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled and needs to be disabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active). (The new test builds might have a fix for this problem. If you try a test build and it works, report here: viewtopic.php?f=6&t=90853, and save the installer file.)

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

Re: VM's wont install

Post by sThorn »

Thanks for the fast response!
I thought both Hyper-V and the AMD-V needed to be active for VirtualBox to work,
seems like i need to do some more reading on how thees techs work together.

I disabled Hyper-V and booted my machine, seems to work now, thank you!


i found this in the logs:

Hyper-v is the name of a rival piece of software, it would hardly be a prerequisite!

Both Hyper-v and VirtualBox need the hardware feature: AMD-v. If Hyper-v has already grabbed it then VirtualBox has to try to negotiate access with Hyper-v, which currently often doesn't go very well.

Executive summary: if you don't need both Hyper-v and VirtualBox then ditch one.

Thanks for the answer.

Does this also meanI can't run Docker and VirtualBox on the same Windows machine at the same time,
and I should rather build my Docker/Kubernetes kluster with hosts it VirtualBox?

I think Docker needs Hyper-V, so for now you'll have to toggle between Docker and Virtualbox using the tenforum switch: https://www.tenforums.com/tutorials/139 ... puter.html

Running Docker inside a Virtualbox guest will be nested virtualization, I think. Depending on your physical CPU, you might be OK doing that or it might be a nightmare. You can tell from a Virtualbox guest log whether your CPU has the services it needs to make nested virtualization work:

You want (1)'s where the (?)'s are now.

Or figure out how to run Kubernetes directly in a Virtualbox guest instead of going through Docker, if that's possible.

Not by itself. I'll try and explain the backgrounds:

Docker Engine is a native Linux application that doesn't need any hypervisor at all. If you want to use Docker on Windows/macOS instead, you install Docker Desktop for Windows/Mac, which implicitly uses the OS's native hypervisor framework (Hyper-V, Hypervisor.framework) to create the needed (hidden) Linux environment.

I'd try and disable Hyper-V on the Windows host, create a VirtualBox Linux VM, and install Docker Engine (docker-ce) inside. Note that if you want to run e.g. an Android emulator inside a Docker container, it will need KVM, and then you'll have to cope with nested virtualization. VirtualBox claims to support a KVM guest inside a VirtualBox VM, so this could work. I haven't tested it personally yet, though.

Thanks for the clarification, fth0. I haven't run Docker yet myself.
