Can't start my Windows XP ISO/VM because KVM
Submitted by Jean-François Fortin Tam
On my F21 desktop currently I see a Win XP VM present in boxes' list (probably tried to create it back in January 2015), but if I try to start it, Boxes just gives me a rather unhelpful 'Could not start "Windows XP SP3"' error message revealer/infobar thingy.
Running boxes from the terminal gives me this (the UI should have presented that error to me and allowed me to copy-paste/report it, btw :)
Boxes-WARNING **: machine.vala:576: Failed to start Windows XP Pro SP3: Unable to start domain: unsupported configuration: Domain requires KVM, but it is not available. Check that virtualization is enabled in the host BIOS, and host configuration is setup to load the kvm modules.
That error makes little sense to me as a user. GNOME Boxes sometimes ran fine at some points in the past. Now it doesn't and as a user I have no clue about this KVM thing. All I know is that I have a Core2 Quad Q9300 CPU that does support virtualization and that it's enabled in the BIOS (why would I ever want to disable that? :) and that, as a point of comparison, VirtualBox runs fine with the same hardware/OS/etc.
