i've make changes in my layout (movig devices) /sys/kernel/iommu_groups: http://sl1pkn07.wtf/paste/view/2a354adf lspci -vt: http://sl1pkn07.wtf/paste/view/03c505d1 sudo lspci -vvv: http://sl1pkn07.wtf/paste/view/79cf804d lstopo(gui): http://wstaw.org/m/2016/01/07/Screenshot_20160107_225933.png lstopo(text): http://sl1pkn07.wtf/paste/view/1ebef006 dmesg: http://sl1pkn07.wtf/paste/view/47a6221a because I found how is the pci layout of my mobo (http://forums.evga.com/FindPost/1945895) Odd slot use only Even slots added --------------------------- ------------------- X16 -- NF200 -- X16 (Through NF200) -- X16(X8) SLOT 1 | | | ------------- X8 SLOT 2 | ------- X16 (Through NF200) -- X16(X8) SLOT 3 | ------------- X8 SLOT 4 X16 -- NF200 -- X16 (Through NF200) -- X16(X8) SLOT 5 | | | ------------- X8 SLOT 6 | ------- X16 (Through NF200) -------- X16 SLOT 7 then, my new layout is: (older layout: http://sl1pkn07.wtf/paste/view/bf647f32) slot1 -> GTX 770 (host) slot2 -> empty slot3 -> empty slot4 -> LSI SAS controller (8x) (host) slot5 -> empty slot6 -> Asus U3S6 (USB3 and SATA6 card) (conected to VM disk) slot7 -> GTX TITAN Black (guest) then. have a good isolation like a newer machines? (each pci isolated) i think (now) yes. but if any expert can confirm this....
