Hi everyone,
        I want to assign a PCI device directly to a VM (PCI passthrough) in a 
machine that does not have VT-d. I found something related with 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.kvm.devel/18722/focus=18753. I 
am wondering if this is included or are there plans to include it in the latest 
KVM version?
  
Although it had worked for us out of tree, there is no immediate need to 
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.

Regards,
Dor

Thanks in advance,
