Thanks Samy, I assume these lines are the ones you're referring to: Oct 22 18:30:35 username kernel: DMAR-IR: [Firmware Bug]: ioapic 2 has no mapping iommu, interrupt remapping will be disabled Oct 22 18:30:35 username kernel: DMAR-IR: Failed to enable irq remapping. You are vulnerable to irq-injection attacks.
These messages indicate that either your hardware is missing features or the firmware tables that describes the hardware is missing descriptions for the feature. The summary is that you should not use I/O pass-through for some devices on this system when you use virtualization systems such as kvm, virtualbox, xen, or vmware. As for the original issue about "Ask each time", I hope someone from the desktop teams can take a look.
