Включение IOMMU для проброса PCI в KVM

В списке можем наблюдать, что IOMMU отключен в ядре. Включим его, для этого добавим intel_iommu=on в конфигурационный файл GRUB /etc/default/grub:
GRUB_CMDLINE_LINUX="... intel_iommu=on"
А затем обновим конфигурацию загрузчика:
grub2-mkconfig -o /boot/grub2/grub.cfg
Перезагружаем систему и проверяем.

Приветствую! Купил новый системник для Ubuntu c kvm — asrock z97 itx, i5 4460. Не получается пробросить pci.
делаю так:
1. биос последний, VT-d enabled
2. в /etc/default/grub добавил
3. проверяю
подскажите, это значит работает или нет?
далее по инструкции добиваюсь
добавляю устроиство в virt-manager и получаю ошибку
в чем косяк? спасибо

maxsagitov,
Вы пытаетесь пробросить USB controller??
maxsagitov
chemtech,
в этом примере да, тоже самое получаю при попытке пробросить radeon r370. Пока думаю на то что система не полноценно видит iommu. при отключении vt-d в uefi вывод dmesg путой. читал что если все ок, /sys/kernel/iommu_groups не пустая. что там должно быть незнаю, но у меня чисто

maxsagitov,
В BIOS Intel Virtualization Technology что стоит?
kvm-ok что показывает?
Так попробйте
GRUB_CMDLINE_LINUX=»max_loop=64 iommu=pt iommu=1″
и
sudo update-grub
maxsagitov
chemtech,
смена строки grub не помогла. это вариант для amd наверное

Получилось завести. Только мой radeon x550 видимо не поддерживает проброс, винда видит, но дрова не ставит.
Отвечаю на свои же вопросы, мжт пригодится кому.
1. вроде, помогла строка в grub
GRUB_CMDLINE_LINUX="max_loop=64 intel_iommu=on vfio_iommu_type1.allow_unsafe_interrupts=1"
2. при проверке iommu должно быть:
3.
… читал что если все ок, /sys/kernel/iommu_groups не пустая. что там должно быть незнаю, но у меня чисто

Имею при себе хост на debian 8 и proxmox 4.4 и виртуалку с windows 8.1, куда и планирую пробросить видеокарту.
Видеокарту geforce 210 и процессор xeon e5645 x2, а так же мать x8da6 supermicro
Пытаюсь пробросить видеокарту по https://pve.proxmox.com/wiki/Pci_passthrough
1. В /etc/default/grub изменил GRUB_CMDLINE_LINUX_DEFAULT=«quiet»
на GRUB_CMDLINE_LINUX_DEFAULT=«quiet intel_iommu=on»
выполнил update-grub
После ребута проверил работоспособность dmesg | grep -e DMAR -e IOMMU
[ 0.000000] DMAR: IOMMU enabled
2. В /etc/modules добавил
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd
3. IOMMU interrupt remapping
выполнение скрипта с результатом:
No interrupt remapping support found соответственно dmesg | grep ecap ничего не выдал
4. Verify IOMMU isolation
find /sys/kernel/iommu_groups/ -type l
Выдаёт пустоту.
1) move the card to another pci slot
Карту перемещать не стал.
2) add «pcie_acs_override=downstream» to grub options, which can help on some setup with bad ACS implementation.
Параметр добавил в GRUB_CMDLINE_LINUX_DEFAULT=
5. Конфиг виртуалки, который в итоге получился
