I found something related wit= h this in a presentation done at the 2008 KVM Forum called 1-1 mapping = and a patch for this at http://thread.gmane.org/gmane.comp.emulators.kv= m.devel/18722/focus=3D18753. I am wondering if this is included or are = there plans to include it in the latest KVM version? > > =20 Although it had worked for us out of tree, there is no immediate need t= o=20 pursue it. If anyone would like to nurture these patches he is more than welcome. ps: you also have pv-dma option for Linux guests (same status though). As time goes by most host will have either vt-d or amd iommu.
