similar to: SR-IOV pool with static MAC address and vlan

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>

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?

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

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> 

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 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, I've been using libvirt (versions 0.9.11.5, and recently upgraded to 0.10.2), and have been attaching an SR-IOV VF to my VM with the following device configuration: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x07' slot='0x10' function='0x0'/>

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

Hello everyone, I'm having problem with SR-IOV transparent VLAN. My host is Fedora 22 and my guest is: pfSense 2.3. The NIC is Intel 82576. I'm using pfSense Packet Capture to check the packet and find that inbound packet still have the vlan tag. The outbound packet seem fine because the router can receive DHCP discover packet from the guest and then send DHCP offer and ARP request

Hi Ashish, I have tested with your xml in the first mail, and it works for rx_queue_size(see below). multiqueue need to work with vhost backend driver. And when you set "queues=1" it will ignored. Please check your qemu-kvm-rhev package, should be newer than qemu-kvm-rhev-2.9.0-16.el7_4.2 And the logs? tx_queue_size='512' will not work in the guest with direct type interface,

hi everybody I'd presume virsh makes the best possible choice, right? It is that just seems bit... odd having realtek in guest and Intel's VF on host, no? regards
