Installing Mac Os Monterey on Mac Pro Host with Ubuntu fail

[Skeuds]

Hi everyone,

I have a macbook pro 15" host on which i have installed ubuntu 22.04 as main OS few months ago.
To allow using osx applications, i need to setup Mac Os Monterey guest with virtualbox but it failed each time i try.

If you could help me it will be very appreciated

You will find my log file attached

Thanks.

A zipped log almost always fits in one attachment, Please edit and try again.

Since you do have a real Apple computer, this Mac guest seems to abide by Apple's EULA. We'll need a Mac guru to weigh in here, to get you going.

One thing I saw in the first section of log is that the VM guru meditated right away. Check that your Linux host OS does not have a KVM hypervisor enabled.

I can see i have kvm installed with the following command :

$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

What do you recommand ? Uninstall KVM ?

Thanks for the zipped full log.

I'm no Linux guru, so I don't know if this:

$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used

satisfies this:

Check that your Linux host OS does not have a KVM hypervisor enabled.

You could web-search the question or wait for a Linux guru to answer.

What do you recommand ? Uninstall KVM ?

VirtualBox cannot run a VM while QEMU/KVM is simultaneously running a VM, and your VBox.log files has the typical indications of the kvm kernel modules being in use. It would suffice to prevent that, but there have been reports that the kvm kernel modules were still in use after running a QEMU/KVM VM, so it might be tricky to achieve that. Uninstalling KVM is a way to ensure that.

Hi,

Hi,
I have finally uninstall Qemu and after that all works like a charm.
But i finally remember that Qemu is used by Docker Desktop and i have to reinstall it.
So i think if i exit Docker Desktop before launching any virtual machine on Virtualbox it could works.

Thank you for your help !

So i think if i exit Docker Desktop before launching any virtual machine on Virtualbox it could works.

If that doesn't work, look for a way to manually unload the kvm kernel modules after exiting Docker Desktop (that's the tricky part I mentioned previously).
