similar to: bridge + SR-IOV guests with KVM

If I'm using the SR-IOV Pool assignment method (from http://wiki.libvirt.org/page/Networking#Assignment_from_a_pool_of_SRIOV_VFs_in_a_libvirt_.3Cnetwork.3E_definition ), how would I check how many virtual functions are already in use? Is there a method other then looping through all the active guests and determining if they're using the SR-IOV interface?

Hello, CentOS 7(1) I like to setup a new Server with SR-IOV for Networking.. I have a I350 Network Card on Board. But on my System this is, I mean, not correct working ? When I like to have Virtual Network Cards I have to unload / reload the "igb" driver? afterward I have my virtual Network Cards. Have any a way, to have the virtual Network Cards on boot time? Thanks for a

Hi guys. These days I'm doing research on SR-IOV & Live migration. As we all know there is big problem that SR-IOV & Live migration can not exist at the same time. I heard that KVM + SRIOV + MacVtap can solve this problem. So I want to try. My environment: Host: Dell R610, OS: RHEL 6.4 ( kernel 2.6.32) NIC: intel 82599

Is there a setting to allow/disable spoof checking and trust on VF from SR-IOV device? Lookin at https://www.libvirt.org/formatdomain.html#elementsDriverBackendOptions can this be done through the driver element? *<driver name='vhost' txmode='iothread' ioeventfd='on' event_idx='off' queues='5' rx_queue_size='256' tx_queue_size='256'>

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'm on a Dell VEP 1405 running Debian 9.11 and I'm running a few tests with various interfaces given in PCI passthrough to a qemu/KVM Virtual Machine also running Debian 9.11. I noticed that only one of the four I350 network controllers can be used in PCI passthrough. The available interfaces are: *# dpdk-devbind.py --status Network devices using kernel driver

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 Brian Hope the following can help you. [root@sriov2 images]# virsh net-dumpxml hostnet

Hi all. I'm try to find answer for my qustion in google, but i can't. if i use openvswitch virtualport in domain and want to use sr-iov does it possible? Or if i use sr-iov traffic not goes to openvswitch? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

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, This is regarding SRIOV in Rhel7. I have added intel_iommu=on in grub.cfg file. When I attach Virtual Function to VM and I try to poweron the VM, I get the below error: [root@Dell-Rhel7 ~]# virsh start rhel64x64GA error: Failed to start domain rhel64x64GA error: internal error: early end of file from monitor: possible problem: qemu-kvm: -device

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

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 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

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
