Welcome, my dear Intel friends:) Last year, community has contributed code regarding to add PCI passthrough into CloudStack, see the patch: https://reviews.apache.org/r/12098/, but unfortunately, this patch doesn't get checked in, due to lack of support from committer: http://markmail.org/message/ux2ojhxfqwdvz2uc. If you guys want to pick it up, either work from scratch, or based on the original patch, that will be great.
