similar to: libvirt -- add virtio-scsi disk with scsi-generic

Greetings, I was wondering what is the proper way to configure a scsi cdrom pass-through so in when the qemu line is generated, host_Cdrom will be used instead of host_device. looking at https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_block.c#L1090, I see that hostcdrom must be true. in order for that to be true, the following must be (see

http://libvirt.org/formatdomain.html#elementsHostDevSubsys At this description used "drive"-typed address for SCSI. But when i get xml-description of scsi-devices by <code> unsigned int flags = VIR_CONNECT_LIST_NODE_DEVICES_CAP_SCSI_HOST ; int ret = virConnectListAllNodeDevices (currWorkConnect, &nodeDevices, flags); then get by

Thank you for your reply, I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc. I took the address details from: # ll /sys/bus/scsi/devices/7:* lrwxrwxrwx 1 root root 0 Feb 8 12:58 /sys/bus/scsi/devices/7:0:0:0 -> ../../../devices/pci0000:00/0000:00:03.0/0000:08:00.1/host7/rport-7:0-0/target7:0:0/7:0:0:0 lrwxrwxrwx 1 root root 0 Feb 8 12:58

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:

Hi Cole & Michal, I'm sorry for my late response, I just end my journey today. Thank your response, your suggestion is very helpful to me. I have added Michal in this mail, Michal helps me review my initial patchset. (https://www.spinics.net/linux/fedora/libvir/msg191339.html) All concern about this feature is the XML design. My original XML design exposes more details of Qemu.

Hi! I'm oVirt developer responsible for most of 'hostdev' support. While working on SCSI passthrough (that is hostdev type='scsi'), I've encountered few issues I'm not sure how to solve somewhat effectively and nicely. Just a note - oVirt by default disables 'dynamic_ownership', meaning we have to handle endpoint ownership/labeling ourselves. This is not

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would

This series implements virtio-scsi queue steering, which gives performance improvements of up to 50% (measured both with QEMU and tcm_vhost backends). The patches build on top of the new virtio APIs at http://permalink.gmane.org/gmane.linux.kernel.virtualization/18431; the new API simplifies the locking of the virtio-scsi driver nicely, thus it makes sense to require them as a prerequisite.

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'

Hi! Report from my multipath tests today. My test virtual machine, that runs from an NPIV pool, is not able to use multipath. When I pulled the cable from one of the targets, it crashed. But, strangely, it could boot up again on that other path, that it just crashed on. That tells me it can use both paths, and is not limited to one of them only, but because the multipath layer isn't

Hi everybody. I have an HP StorageWorks array connected to one of my servers, connected via an LSI controller (lspci reports: SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)) on an HP DL385 running CentOS 5.5 x86_64. I have set up multipath and all is working but, when I create a snaphost and export it as a new LUN from the HP web interface, it

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is

When you pass a device in the pci chain (after virsh nodedev-dettach'ing it from host) to the guest, how much is passed without being emulated/abstracted?
