I've never had hardware to be able to properly test this. As soon as I did, I was planning to test using: http://fedoraproject.org/wiki/Features/SR-IOV#How_To_Test Can you verify that your NIC is in fact supported, and that you followed the steps there (in particular using 'max_vfs=7' when loading the igb module)? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/741706 Title: could not add physical hardware (ethernet card) -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 741706] Re: could not add physical hardware (ethernet card)
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.

[Bug 741706] Re: could not add physical hardware (ethernet card)
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. ** Changed in: libvirt (Ubuntu) Status: New => Incomplete ** Changed in: libvirt (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/741706 Title: could not add physical hardware (ethernet card) -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
