similar to: PCI passthrough and abstraction

So I am reading through , and am wondering what is the difference between <hostdev mode='subsystem' type='pci' managed='yes'> <hostdev> and <interface type='hostdev' managed='yes'> </interface> if I am trying to give full access to a NIC? Which one exposes more of the card? On Wed, Apr 24, 2019 at 1:13 PM Mauricio Tavares

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>

In trying to find out why my usb passthrough is not working, I decided to edit (virsh edit) the config file for the vm client, removing the following lines <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x051d'/> <product id='0x0002'/> </source> </hostdev>

Good morning, there is a typo in my description; the line <address domain='0x0' bus='0x1' slot='0x00' function='0x0'/> should be <address domain='0x0' bus='0x2' slot='0x00' function='0x0'/> That was correct in my xml-file. Isn't there anybody how can help me with that? Regards Michael Weis Von:

Hi, how can I define passthrough of all USB-slots to a guest with libvirt? With qemu it's very easy: # kvm -usb -usbdevice host:0.* -usbdevice host:1.* -usbdevice host:2.* -usbdevice host:3.* ... This configuration of the VM gets *all* 4 USB-Slots. Every time somewhat USB-device is plugged in the VM gets it. virt-install manpage offers: --host-device 001.003 USB by bus, device

Hi Pierre, thanks for your reply. I am using kernel 3.10.0-123.8.1.el7.x86_64. The kernel modul used after nodedev-detach is vfio-pci This is the output of lspci -vv after I did a virsh nodedev-detatch pci_0000_02_00_0 02:00.0 Ethernet controller: PLX Technology, Inc.

Perhaps a bit off-topic (I asked on the rescue list -- http://web.archiveorange.com/archive/v/OaDWVGdLhxWVWIEabz4F -- and was told to try here), but I am kinda shooting in the dark: I have been finding online scattered and vague info stating that this card can be made to work with a sparc solaris 10 box (http://old.nabble.com/eSATA-or-firewire-in-Solaris-Sparc-system-td27150246.html is the

I have been following the patches on nvme support on the list and was wondering: If I wanted to build a vm host to be on the bleeding edge for nvme and spdk fun in libvirt, which linux distro -- fedora/ubuntu/centos/etc -- should I pick?

Trying to start one of my vms, a centos one at that, but am getting the following message: [root@vmhost ~]# virsh start voip --paused error: Failed to start domain voip error: cannot open file '/var/tmp/FreePBX-5.211.65-3-x86_64-Full-1388073872.iso': No such file or directory [root@vmhost ~]# But, virsh dumpxml voip shows no info onto the .iso <disk type='file'

So I have an entry for a USB device ( ID 051d:0002, UPS) I want to use with a given vm client. In that vm client's config file I added something like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x051d'/> <product id='0x0002'/> </source> </hostdev>

Hi, I'm trying to attach a host FC HBA to VM (NPIV). Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA. I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device. Also, when trying to attach the device manually as a live device - I get:

I have been investigating pci pass-through for virtualized guests and the documentation I have found seems to me to lack a certain consistency in its example. This may be due to my not understanding what it is trying to inform me. What I wish to do is to configure a pci multi-port serial i/o card for use by a single virtual host. I start by running lspci -v on the host to identify the serial
