Re: [libvirt] [PATCH 10/12] virCaps: Introduce IOMMU and VFIO capabilities

There's no need to check for these two host capabilities on each device attach or detach. It's sufficient to check them on the daemon start and then just query them from virCaps when needed. Moreover, this way it's fairly simple to expose them in capabilities XML.
