[PATCH 3/4] PCI: support SR-IOV capability Support SR-IOV capability. By default, this feature is not enabled and the Physical Function behaves as normal PCIe device. After it's enabled, each Virtual Function's PCI configuration space can be accessed using its own Bus, Device and Function Number (Routing ID). Each Virtual Function also has PCI Memory Space, which is used to map its own

Hi, (Already asked this on the intel wired forum: http://communities.intel.com/message/185413#185413 but some of those questiones are XEN specific, which might be why theres no response ;-) I have doubts if SR-IOV will provide the required features compared to nPAR. SR-IOV seems more flexible, but I''m not sure if performance and features are the same as nPAR. Servers will be Dell M620

Hi Paul, You can set the static MAC address and VLAN in the interface section of the VM xml. So it will not change even when the VM shuts down and restarts. VM interface xml: <interface type='network'> <mac address='52:54:00:85:e2:cd'/> <source network='hostdev_net'/> <vlan> <tag id='42'/> </vlan>

Hi I am trying to do passthrough to guest using sriov and libvirt I tried to use both techniques from here http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E <http://wiki.libvirt.org/page/Networking#Assignment_with_.3Chostdev.3E> Assignment from a pool of SRIOV VFs in a libvirt <network> definition Assignment with <interface

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:

I have an Intel X540 SR-IOV NIC in a box with ACS support running RHEL6.4. Hi Hongming, I'm hoping you can please help with two issues: 1. The pool works, but I transparent VLAN with the pool does not. I have to manually run "ip" afterwards to get it to work. # virsh net-dumpxml em2net <network connections='1'> <name>em2net</name>

Hi all, How do you add a VLAN tag to a libvirt SR-IOV VF network usingthe "virsh net-update" command? I couldn't find the section to passto the "virsh net-update" command to add the VLAN tag. I have the following libvirt network defined for a SR-IOV VF: <network>  <name>GE0-0-SRIOV-1</name>  <uuid>7bc67166-c78e-4bcf-89ee-377dd9086631</uuid>

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

Hi Laine, Thanks for taking the time to respond to my question. I think I have not described my problem clearly. Let me explain my issue below with the information that you had requested. My assumption according to the information you gave me is that the admin MAC and VF MAC are the same in my case. I see a PF (GE0-0) interface but I don’t see a vfnetdev interface as you mentioned in your
