Dear all,
I tried to enable IOMMU for PCI-Passthrough. I tried with three different machines, all of them now crispy fresh. Nevertheless as I had the same result
with in total three boards and CPUs but it is the same picture in all cases, so I wanted to ask whether maybe I made a general mistake.
The combos are:
Best Regards,
Carsten.
I tried to enable IOMMU for PCI-Passthrough. I tried with three different machines, all of them now crispy fresh. Nevertheless as I had the same result
- IOMMU not working, there are no IOMMU device groups, popup complains
- but no real error found in dimes, in fact it is the absence of DMAR messages
- switched on virtualization, but all boards only have that and don't distinguish between VT-x and VT-d
- am on grub and added intel_iommu=on in /etc/default/grub and it made it into the log and /proc/cmdline
- added the modules in /etc/modules
- also tried combinations of iommu=on, iommu=pt, allow_unsafe_assigned_interrupts=1
with in total three boards and CPUs but it is the same picture in all cases, so I wanted to ask whether maybe I made a general mistake.
The combos are:
- Asrock P5B-DE with E5700 which is clearly not working (CPU doesn't support VT-d)
- Intel DH67CL with i5-2600T with latest 2018 BIOS
- Gigabyte GA-Z68MX-UD2H-B3 with i7 2700K and latest UEFI BIOS
Best Regards,
Carsten.
