Hi, all who read this post ![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
since two/three days I'm struggling with PCI Passthrough,
my Server has 4 Onboard NICs (Ethernet Cards) and I want to Pass two of them to my VM.
IOMMU is alredy enabled
and PCIs are in seperated groups, (
i also added "[14e4:1657" to /etc/modprobe.d/kvm-intel.conf
which doesn't make a lot of sense since all the NICs have same Vendor-: Device ID, but wanted to test it (didn't work)
and at the end
any idea what I'm doing wrong?
I'm fairly new with Linux, so please give more hint when you need any command output or any action from my side,
Thank you all![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
