SRIOV test on Xen with Intel 82576
Hi, I am working of Intel 82576 device to test the SRIOV functionality. I want to assign VFs to a VMs(domU) and verify the control and data path. I installed Xen-unstable with 2.6.30-rc3(dom0). But the SRIOV functionality isn''t working, because MSI is not supported. Please let me know, what version of Xen and dom0 supports above functionality?...

[libvirt] SRIOV configuration
Hello, We encountered a problem while testing SRIOV on kubevirt [1]: We are currently using the Device "hostdev" generic options to pass-through the VF to the guest. It is not done through the "interface" (with type hostdev) because that option requires access to the PF which is not available in our case (the VF is moved to the...

Trace SRIOV NIC''s MSI-X delivery to Xen
Hi all, I''m using Xen4.0.1 with SLES11SP1 with Intel''s SRIOV NIC in passthrough mode to FedoraCore14 guest HVMs. From guest HVM I''m able to send packets out but not able to receive the same. Intel NIC HW counters are reporting receiving packets but the same is not reaching the guest HVM. My NIC uses MSI-X to report packets to SW. which should b...

Currently I'm not familiar with the PM part. But I still think the sriov capability should be handled by PCI core. I'm trying to understand all the relevant code.. For your question, based on what I found from the code currently, I guess the sriov capability will be restored b...

bridge + SR-IOV guests with KVM
Hi, I managed to get SR-IOV with an Intel I350 NIC to work.For this I followed the documentation on this page: https://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition But as I have more VMs then VF on the NIC I also have a bridge wich serves the other guests. As I run Debian Buster as host I followed the documentation here: https://wiki.libvirt.org/page/Networking#Debian.2FUbuntu_Bridging If I use only the SRIOV ever...

automatically detaching PCI host devices from guest for SRIOV usage.
Dear List , We are using intel 82599EB based SRIOV capable 10GbE cards on the host machine.The VFs are being assigned to the guest in pass through mode and are providing the network connectivity as expected. However when we shutdown the guest the connectivity does not comes back via the VFs on the guest in next boot unless the VFs are detached f...

Once they are allocated, virtio driver doesn't have to care too much about how to manage them. The proposal for the spec is just to provide a feature bit based virtio way for virtio drivers to know whether a virtio device is SR-IOV capable (and virtio driv...

question about libvirt network Xml
Hi, I’m an openstack developer trying to use Assignment from a pool of SRIOV VFs in a libvirt <network> definition from this link http://wiki.libvirt.org/page/Networking My question is is it possible for nova (the openstack compute) to know which VF out of the pool will be allocated to a VM before it invokes libvirt to launch it? Thanks In advance, Robert

You have two choices for the backup virtio interface: 1) it can be a macvtap device connected to the PF of the same SRIOV device. 2) it can be a standard tap device connected to a Linux host bridge (created outside libvirt in the host system network config) that is attached to the PF (or alternately one of the VFs that isn't being used for VMs, or to another physical ethernet adapter on the host that is connected...

SR-IOV: no traffic isolation between VFs with Broadcom 10Gbps cards
Hi all, I'm testing on debian/unstable SR-IOV feature with Broadcom BCM57810 cards and KVM hypervisor: Compiled against library: libvirt 1.2.1 Using library: libvirt 1.2.1 Using API: QEMU 1.2.1 Running hypervisor: QEMU 1.7.0 bnx2x -> firmware 7.8.17 -> driver from kernel 3.12.7 8 VFs are created on the first PF. For each VF, a specific mac address is set manually using "ip
