Hi @pandom79 so there is a bug in virt-manager GUI.

If you start creating new VM in the Step 2 at the bottom page you can select operating system that will be installed inside the VM. Based on the selected OS virt-manager picks q35 or i440fx. If it defaults to i440fx virt-manager gets domain capabilities from libvirt for i440fx only.

Later in the customize window if you switch chipset to q35 virt-manager will not refresh domain capabilities so it will not update the list of firmwares which is the bug here. The same happens the other way around. We need to fix it to refresh domain capabilities correctly when user switches chipset in the UI.

So there is an issue how QEMU is installed in Void Linux and there is a bug in virt-manager to not show correct firmwares if chipset is changed. I'll fix the virt-manager bug.
