I have installed Gnome Boxes from flathub, but it does not work. I’m getting the following message when starting it: “Boxes cannot access the virtualization backend”. In the terminal I can see the following:
$ flatpak run org.gnome.Boxes

I am running gnome-boxes from the rpm-ostree repository and it works. It looks like the flatpak is missing some dependencies, or it might not be set up right for permissions to access the kvm or libvirtd services. You should probably open a bug report on the flatpak.
I didn’t try boxes in the last 6 months, but the last time I tried it, I was not impressed. It is designed to be easier to run than virt-manager, but it still seems to have some bugs (like having a hard time connecting it to libvirtd/kvm), which appear on all distros it is installed.
I would also stick to virt-manager, though it is a bit more complex, because it provides a loot of features and gives a lot of control.
What version of Silverblue + Boxes are you using? I was just able to successfully install Boxes and run it on Silverblue 29, with no additional setup needed. There were some errors reported, but nothing fatal.

Have you used virtualization before on this system? In case you haven’t, you can see if it is enabled by checking /proc/cpuinfo:
$ grep -wo -e vmx -e svm /proc/cpuinfo
It’s possible that the virtualization options are disabled at the BIOS level, so you might have to check in there as well.
This all supposes that Boxes is actually looking for these kinds of CPU flags, etc to enable virt support and is the root cause of the issue…but I could be sending you off in the completely wrong direction.
Virtualization seem to be enabled (I get vmx several times as output) and /dev/kvm is also there.
I was hoping, perhaps naively, that gnome-boxes would “just work” when installed as a flatpak. Do I have to set up any groups or something like that? I remember having to add myself to the libvirt group previously in order to run for example vagrant…?
I don’t know a lot about Boxes…but my test was done in a VM with a clean install of Silverblue 29…and now that I look closely, it doesn’t even have the virt flags on the CPU in the VM.
So I was just able to install it and run it successfully out of the box without any modifications. I know this doesn’t really help you any, but just reporting my own results.
The flatpak should work by itself, no need for any extra setting. Some users seem to have permission issues with access to /dev/kvm, so you might want to check whether your user has r+w access to it, just like @billyb stated above. The flatpaked Boxes ships with its own libvirt daemon in the sandbox, so nothing you’d install with rpm-ostree will affect it. It would help me debug if you could share the output of
@feborges just replaced regular Fedora 29 with a clean installation of Silverblue 29. Boxes indeed works out of the box for me. Mostly.
I migrated a Windows 10 guest that I had on my old installation and it turns out screen auto-resizing of Windows no longer works, despite the guest having the QEMU guest agent. I vaguely remember having to install some additional server-side drivers on the Fedora host to get to work properly. Are some server parts missing in this Flatpak?
If you’re still using Wayland, try switching to GNOME on Xorg (or the other way around). I’ve had all sorts of annoying issues with Wayland - they’re probably GPU-related.
Does not seem Wayland or GPU related. Windows works just fine. I can set the resolution of the Windows guest to anything available and it’s fine. It just won’t automatically resize like it used to do with proper host ↔ guest communication. So it’s likely Flatpak related…
This installer contains some optional drivers and services that can be installed in Windows guest to improve SPICE performance and integration. This includes the qxl video driver and the SPICE guest agent (for copy and paste, automatic resolution switching, …)
I am now subscribed to the discourse notifications so I can get back to you faster.
It was already there from when I ran this same VM on my old host for the last 2 years, where automatic resolution switching worked just fine. I removed it and reinstalled it but no effect. I have copy/paste integration and even WebDav drives, but no automatic resolution switching.
Windows Device Manager is telling me it’s using “Microsoft Basic Display Adapter” though. Remarkably there is no mention of the QXL driver.
I had the same issue with Boxes in Silverblue as the flatpak, and installed the tools manually. It will go through the motions of installing the guest tools, but I think it fails silently somewhere. I ran the flatpak from the terminal and got the following
And the list goes on.
Boxes loads, but the tools don’t appear to help me with USB ports with network devices. So I followed @znmeb regarding layering Boxes and when I did Virt-Manager began working, where before it was complaining about libvirt???-sock not accessible as if it is there but no permission to access. The USB ports are recognizing the communication cables I use now.
I too have given up on running Gnome Boxes right now. Besides the QXL driver issue, Windows 10 is simply unusable because it lags and hangs. While Windows itself isn’t too bad, both Internet Explorer and Word become unresponsive every few seconds. The mouse pointer becomes a spinner, indicating it’s doing something and the windows just become white squares.
Given all the feedback from everyone here I can’t escape the feeling that this is Flatpak related…
