Hello,
I have an issue managing the iGPU passthrough feature on my tiny thinkcenter M73 (CPU : Intel(R) Core(TM) i3-4150T CPU , having an Intel® HD Graphics 4400 )
Currently im running
Currently i've used this
On a forum i've found and extra step do to :
Unfortunately after adding the PCI device from the list even if in the command "dmesg | grep -e DMAR -e IOMMU" the meesage is "DMAR: IOMMU enabled" on the web GUI i cannot star the VM due to message "TASK ERROR: cannot prepare PCI pass-through, IOMMU not present" . I've tried a few things found on google but none succeed.
I managed to find another error on my trials that kinda looks like the other one.
What can i do / that would be the idea to tackle with this issue ? Im trying to passthrough to a W10 X64 VM
Other info :
lspci -v command returns :
Thank you for your time,
Alex
