The PCI slot / function in the libvirt XML should match, but the "bus" number in

Hi Laine, For the feature testing before, I only test the linux bridge setting as in 2), it works. Now I tried 1), to use macvtap bridge mode connected to the PF, it can not work as the hostdev interface can not get dhcp ip address on the guest. Check on host, the /var/log/messages and dmesg both says: "Jul 6 04:54:45 dell-per730-xx kernel: ixgbe 0000:82:00.1 enp130s0f1: 1 Spoofed packets

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 from the *guest* *before* initiating a shutdown of

We are using an Intel 82599 chip that allows 4 PFs ( eth0..3) per VM. I am able to manually start VMs using the hostdev definition for the four network connections, but I'd like to start using the pool approach. Ubuntu 12.04 libvirt 1.0.0 Following: http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition I can get a pool working with

Hi everybody, since long time, I'm using Xen on CentOS with XL, currently latest CentOS 7 with Xen 4.15 from the CentOS-Xen-Project. For several VMs I have to use SR-IOV, to lower the CPU-usage on Dom0 on the host. CentOS 7 comes to an end, Xen is not supported by RHEL nor RockyLinux anymore, so unfortunately I have to switch to KVM. First step will be now, converting all the scripts for

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 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

Hi laine, I have leave some questions on IRC, but my VPN broken time after time. Please ignore the questions on IRC. In my understanding, the standby and primary hostdev interface may be in different subnet. I'm not sure whether it is correct. Could you please help to explain? Thank you in advance. For example, primary hostdev is connected to vf-pool with <pf='eth0'/>, while

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> 

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? Is there any tool available to manage SRIOV

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
