What other VM’s? I have no need for them.
My point is, that you can’t blame people for not using something that is really cumbersome to work with.

Fair enough, QEMU itself isn’t exactly user-friendly, although wrap it in libvirt + Virtual Machine Manager and it’s great. I’m just wondering if your host machine struggled to run other VMs or if it was just a problem with the L5 VM itself.

It you have VT-x (or AMD-v if using an AMD processor) enabled in the BIOS or UEFI, then Qemu should be fast enough for you to at least try out the Librem 5 image and see what works. Of course, it is going to be slower and more cumbersome than running that code on an ARM device, but the point is that anyone who has a x86 PC can keep track of the progress Purism is making with the software.

Thanks for trying to help. 
Not sure what went wrong. I installed qemu on a Windows tablet and on a Ubuntu laptop. On both machines the Librem 5 emulation did not progress beyond the start up swirl.
It might be a resources problem, it might be a matter of tweaking some start up parameters. Next time around, I will have a look at a that bios setting. i might get things working in the end.
But at the moment I am mostly just annoyed that I wasted a couple of hours waiting in vain for the bloody thing to get going.
indeed that is what it is at the present moment.
i managed to snag a 512GB Shangsung-Pro NVME (970-pro) back in late-2018 for ~200 $(less if i remember correctly but it was not USD currency so i might mess up the number but not by much)
F*ck! It’s like we never left the nineties…
Why does this:
sudo qemu-system-x86_64 -boot menu=on -drive file=librem5r4.img format=img -vga virtio -display gtk -m 2G -enable-kvm
result in this:
WARNING: Image format was not specified for ‘librem5r4.img’ and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the ‘raw’ format explicitly to remove the restrictions.
qemu-system-x86_64: format=img: drive with bus=0, unit=0 (index=0) exists
If I am not mistaken the format is specified as ‘img’.
So, if you leave out the format specification it runs. That figures…
Let’s see if it results in a working emulation…
(Enabled the VT-x option in the BIOS, btw.
But of course, after that, bugger all happens…
This nice for developers, but you can’t blame regular customers that they do not check out the emulation: it is unworkable.

If I were you, l would read this topic.
Last time I tried I used Gnome-Boxes and it worked like a charm
The .img file is for the Librem 5.
If you are trying to run this on a x86 Linux PC, then you need to be using a qcow2 file. For example:
wget https://arm01.puri.sm/job/Images/job/Image%20Build/5873/artifact/qemu-x86_64.qcow2
sudo qemu-system-x86_64 -boot menu=on -drive file=qemu-x86_64.qcow2,format=qcow2 -vga virtio -display gtk -m 2G -enable-kvm

Thanks.
Wish that sort of info would be documented somewhere.
(And why is the image file named the same as the qemu command?)

To let you know that that one is the one you should use in qemu I guess.

Somewhere that is easier to find (for a non-developer), then, maybe.
And it still seems strange to name an image file the same as the file you use to load said image file.
Anyway. Thanks again. I hope this will finally work.
the developer mind works in mysterious ways …

It works!
Thanks a bundle, amosbatto.
In the end it took just three command lines (an apt-get for qemu, the image download, and the qemu execution), and a bios tweak to get things going. Not that hard. Wish the documentation would have been that helpful. (It could, for instance, be a lot easier to find a link to the right image file.)
The wait for the Librem5 is getting so frustratingly long, that I decided to have a look at an emulator. Would be nice if it was a tad more accessible.

here ! you might find it helpful if you’re messing with QEMU > https://lbry.tv/@DistroTube:2/virt-manager-is-the-better-way-to-manage:b
Thanks, reC. I will check it out.
Yes, the image build page is confusing and there is no stable link to get the latest Qemu image, so you have to hunt for it.
That be a Negative. Today is the 50% mark for the month of Nov. Looking forward to an email soon.
