I was dealing with similar problem like you and today I found the solution for me... maybe it will help you too. set the rights for the device path after that the VM is starting using virtio-pci on pve-kernel-3.10.0-3-pve: 3.10.0-13 :-) (I have added also the PCI STUB to the grub...

This doen't make any sense to me.. if you look at site 282 on Intel spec, the are fully speaking about VT-d support. http://www.intel.de/content/www/de/de/chipsets/7-series-chipset-pch-datasheet.html Basically it works fine until 2.6.32-27, but nothing newer...

Hi all, although nobody could help me, I decided to try instead of Gigabyte GA-H77-DS3H with another Mainboard. After some suggestions I found in the internet , I bought me an AsRock Z77Pro4. The exchange took some time, as it its like to setup new PC.. But afterwards a big disappoitment was...

Hi everyone, as I am having problems using my mainboard GA-H77-DS3H with IOMMU on 3.10 , I'm thinking to switch the board. Does an<one has experience with one of these boards and IOMMU on 3.10? ASRock Z77Pro4 ASRock Z77 Extreme4 As I read, they should work fine, but thas only on WiKi and...

What I'm little bit wondering, do you need to assign the physical interface to the VM or maybe would be enough to create for each ethX interface a bridge and assign that bridges to your kvms using virtio, E1000 or whatever..?

Or alternative if someone can me give an mainboard purposal with intels 77th chipset which is working without issues on IOMMU.. As I read GigaByte is not such one, and seems some Intel's boards neither.

to revert to your old config, you should bootup your old kernel too... pve-kernel-2.6.32-29-pve. (choose in GRUB, or change default in /etc/default/grub and apply)

Thanks but that's not the point. I need it thus I did activate it, and it is unfortunately not working. My last working state is 2.6.32-30, but allready with error messages from the integrated graphics (DMAR:[fault reason 06] PTE Read access is not set) which is not disturbing to pass trough my...

Hi, I was trying to upgrade to 3.10 with IOMMU, but it looks like, mine mainboard is bad one with bugs (I thought I bought something special to me.. ha ha). There is one patch which actually disables iommu for such device tree, which I was hoping could work for me, but I can't apply it as it...

I have the same issue with my Core I7 3770 on H77 chiset. 2.6.32.30 is not working, last working version was 2.6.32.27. Anyway it is affecting only the Intel graphic card and the messages will be stopped after few minutes. My PCI_PASSTROUGH of my DD Cine 6.5 is still working fine. Did anyone...

Hi, does anyone use IOMMU Pass-Trough? Using kernel 2.6.32 it works fine for me, but with 3.10 I get from qemu/kvm following error: kvm: -device pci-assign,host=06:00.0,id=hostpci0,bus=pci.0,addr=0x10: No IOMMU found. Unable to assign device "hostpci0" kvm: -device...

I am having similar problems with new Ubuntu and Windows 2012 R2 too. What I actually do is to change the Video to Standard VGA, this helps a little. But not for mavarics, after 2nd reboot i get the Kernel backtrace. I think there is some issue with the emulated BIOS..

I used the driver above (2.0.0.6) on Proxmox 3.0 (2.6.32-23-pve) too but i go now in heavy load crashes of the NIC so I decided to use backports driver. I took the backports-3.11-rc3-1 from http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/ (for sure you need your headers and...
