Bug#1122845: gnome-boxes: Doesnt't fall back to TCG when CPU doesn't support virtualization

[Juan]

Package: gnome-boxes
Severity: important

Dear Maintainer,

I'm using Debian 13 with KDE and Wayland. My laptop has an Intel Celeron 585
CPU that does not support virtualization.  In that situation, QEMU usually
falls back to TCG when KVM not present.  But with gnome-boxes it doesn't.  It
just says No KVM! and doesn't let me create a VM.  It doesn't even give me the
option for TCG.  This feels like a bug.  I'm not sure though.

Thank you for your time,

Juan
