SR-IOV is not yet working for me, though. I've had to: - [on host] blacklist the igbvf module, so it won't attach to VF devices
- [on host] install QEMU-KVM and libvirt from ppa:nutznboltz/kvm- libvirt-lts (else QEMU fails with 'get_real_device: /sys/bus/pci/devices/0000:05:10.0/vendor: Permission denied'). This might be fixed in Lucid someday -- bug 545795 - [on host] add kernel parameter intel_iommu=on on the host (else QEMU fails with 'No IOMMU found. Unable to assign device "hostdev0"') - [in guest] install -server flavor kernel, because -virtual flavor does not have igbvf driver - [on host] add 'capability sys_admin' in /etc/apparmor.d/abstractions /libvirt-qemu -- else 'igbvf 0000:00:03.0: Failed to initialize MSI-X interrupts.' Final obstacle: - VM stalls (doesn't boot to login prompt). QEMU logs an error: 'kvm_run: Bad address'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/790201 Title: Cannot use SR-IOV feature of Intel 82576 network card -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
