Because IOMMU is a little or a lot of broken in different ways on different boards, so different hypervisors do different things to overcome this problem and “fix” the brokenness of the implementation. I am using an Asrock X58 Extreme with an i7 For pv-ops dom0, you can use pci-stub to hide device. If so, please share your wisdom! No, I haven’t tried that.

Upon boot the initialization gets stuck at “loading initial ramdisk” and does not get unstuck. I noticed then that the i does not actually have VT-d support specified. Support for passing-through multi-function devices as multi-function devices has been merged into xen-unstable and should appear in 4.

Intel says the chipset northbridge? Otherwise qemu-dm will be built without pass-through support.

No memes or potato images. If someone has done this please share your wisdom!

One of the biggest reasons that IOMMU fails to work properly is because it’s extremely concerned with security. Welcome to Reddit, the front page of the internet.

Become a Redditor and subscribe to one of thousands of communities. It is primarily targeted at HVM fully virtualised guests because PV paravirtualized pass-through does not require VT-d altough it may be utilized too.


Just don’t put the graphics card in the last pcie slot as that slot only runs at x4, although it probably wouldn’t matter. Inyel may have to look for someone else in the UK to do the build with better components.

Page 1 of 4. The passthrough tends to piss off the host occasionally, requiring a reboot. Your first sentence, do you mean you can’t say for certain?

For VT-d enabling work on Xen, we have been using development systems using following Intel motherboards:.

As also discussed in Self: Any distro, any platform! This technique is only useful if pciback has been compiled as a module. A back-port to 3. Chipsett in or sign up in seconds. How are you finding that and do you recommend it in general?

Someone has linked to this thread from another place on reddit: If you’re posting for help, please include the following details, so that we can help you more efficiently: It does seem to have too much other crap added to it for my liking. I then read this and this. However, the Core i7 series that have been around since last year, they are only compatible with the X58 and not the P This means that if a function of as multi-function device is passed-through to an HVM domain, it will appear as function zero of a single-function device in the HVM domain, regardless of its physical function number.


The integrated memory controller on the Lynnfield processors support two DDRMHz channels, it’s not a triple memory controller like found on the Core i7 series. I could have kept debugging, as VT-d is supposedly supported at the chipset level via the Northbridge, but I was looking for an excuse to buy one of these anyways, so I did.
