Public bug reported:
There is a bug preventing multiple people with my combination of
hardware from using PCI passthrough. I am not actually sure whether the
bug is in kernel/kvm, vfio or qemu, however, as qemu is the highest-
level of these, I am reporting the bug here as you will likely know
better where the origin of the bug may be found.
When attempting to pass through this device to a KVM using VFIO, this
results in error -14 (Bad Address):
# qemu-system-x86_64 -enable-kvm -m 10G -net none -monitor stdio -serial
# none -parallel none -vnc :1 -device vfio-pci,host=1:00.0 -S
QEMU 2.9.1 monitor - type 'help' for more information
(qemu) c
(qemu) qemu-system-x86_64: VFIO_MAP_DMA: -14
qemu-system-x86_64: vfio_dma_map(0x7f548f0a1fc0, 0xfebd0000, 0x2000, 0x7f54a909d000) = -14 (Bad address)
qemu: hardware error: vfio: DMA mapping failed, unable to continue

This has occurred on Proxmox (Proxmox and Debian packages, Ubuntu kernel), Ubuntu,
and pure Debian packages and kernel on Proxmox. However, this error
reportedly does NOT occur for:
- different distributions(!) (Fedora 24, 25)
- different HBA cards (SAS2308, SAS3008)
- different CPU (E3-1220v5)
I would be thankful for any input and I'll be happy to provide any
further info necessary. This is my first time delving this deep into
anything close to the kernel.
Thanks and best regards,
Johannes Falke

Hello!
Has your problem been solved? I also encountered a similar problem. My ioctl() also returned an error -14(Bad address).

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.
