Let's say I have libvirt [root@vmhost2 ~]# virsh version Compiled against library: libvirt 4.5.0 Using library: libvirt 4.5.0 Using API: QEMU 4.5.0 Running hypervisor: QEMU 2.12.0 [root@vmhost2 ~]# running on centos 8 and then I have this card [root@vmhost2 ~]# virsh nodedev-dumpxml pci_0000_01_00_0 <device> <name>pci_0000_01_00_0</name>

Hello all. We are moving from Xenserver 6.5 environment to KVM because we can't use 10gbe speed in our VM's so we decided to test KVM. To inicial test I've create script, using qemu commands, to build two VM's and test the nic speed. Each VM has one nic, using virtio, into it own bridge. In this bridge we associate one 10gbe physical nic. They can communicate each other. When

Hi, I have a guest enabled vIOMMU, but on the guest there are several devices in the same iommu group. Could someone help to check if I missed something? Thank you very much! 1. guest xml: # virsh edit q ... <os> <type arch='x86_64' machine='pc-q35-rhel7.5.0'>hvm</type> <loader readonly='yes' secure='yes'

Dear all, I'm looking for a bit of help with a problematic VM. We have an hypervisor which has 4 eth ports. 3 are already used, and I wanted to pass the 4th one directly to a VM (which is fully working without it). So, I modified the XML accordingly (which matches our hardware), adding: <hostdev mode='subsystem' type='pci' managed='yes'> <source>

Hi Guys, I am trying to add a Broadcom Physical NIC to a virtual Machine as Passthrough device. However I am getting following error. Error starting domain: unsupported configuration: host doesn't support passthrough of host PCI devices Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 88, in cb_wrapper

Hi, I''m having problems using Xen (2.0.7 and 3.0.0) on newer IBM HS-20 blades, which uses Broadcom network card (tg3 kernel module).

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

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 container namespace where libvirt runs, but not

Hi, We have a HP DL385 G6 server that is having an issue. Two of the 4 network cards are not being recognised by Linux. We have quite a few other servers with the same hardware and no issues but, before I call HP, I would like to make sure that I am not doing anything wrong :) I have tried with the kernel that came with CentOS 5.5 and the updated one kernel-2.6.18-194.11.3. I do an lspci

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

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

Hello all. Again I call upon the greats of this mailing list to help me with an issue related to MEMDISK - notably when paired with various Dell OptiPlex and Latitude systems. The issue presented itself sometime ago and I best dealt with it by remaining with version 3.83 of the SYSLINUX package. But valuing the improved changes fostered by newer versions, I would prefer to move forward with

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

I just kickstarted a new machine with the latest CentOS 6.2 files, including kernel 2.6.32-220.13.1.el6.x86_64. It came up without network interfaces. dmesg says: bnx2: Broadcom NetXtreme II Gigabit Ethernet Driver bnx2 v2.2.1 (Dec 18, 2011) alloc irq_desc for 36 on node -1 alloc kstat_irqs on node -1 bnx2 0000:01:00.0: PCI INT A -> GSI 36 (level, low) -> IRQ 36 bnx2 0000:01:00.0:

hi everybody I'm having I pretty regular setup, so I'd like to think. Guest network is to use passthrough and a DNS+DHCP on a neighbour system gets requests and then DHCP updates DNS records but with libvirt host's name instead of guest's. Am I missing something here? How do make a guest claim DNS update and the not host on which that guest is running? many thanks P.
