The virsh start <domain> fails with qemu error when the hostdevices of the same iommu group are used actively by other vms. It is not clear which hostdev from the same iommu group is used by any of the running guests. User has to go through every guest xml to figure out who is using the hostdev of same iommu group. Solution: Iterate the iommu group of the hostdev and error our neatly in case a device in the same iommu group is busy. Reattach code also does the same kind of check, remove duplicate code as well.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
