I've never had hardware to be able to properly test this. As soon as I
did, I was planning to test using:
Hi Serge,
I tried it with 'intel_iommu=on' kernel option but with the same result.
It does not work.
Does physical hardware assignment for network cards really work under
KVM?
Below my complete dmesg output shortly after I tried to start a VM with
a physical hardware assignment.
Bye,
Michael
Thanks for reporting this bug and helping to make Ubuntu better.
I notice the error messages include:
No IOMMU found.
Did you boot with 'intel_iommu=on' in the boot arguments? If not,
please add that and try again, and let us know whether that worked.
