similar to: accessing USB as storage device through lxc container.

Thanks Martin for the info. I have tried the below snippet in the libvirt xml. <hostdev mode='capabilities' type='storage'> <source> <block>/dev/sdc1</block> </source> </hostdev> ------------ root@ir800-lxc:~# mount /dev/sdc1 /mnt/usbdr/ mount: permission denied (are you root?) ---------- It works if the

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

I'd also like to point out that, when setting up a linux container with _just_ the lxc tools available in ubuntu, all that was needed to be done was whitelist the appropriate cgroups for the Android devices. The lxc tools seem to create the appropriate character devices when you detach/attach the Android device via USB, and the Android `adb` tool recognized the devices. So, a tangential

I'm using a bit of a different keyboard, the infinity ergodox [ https://input.club/devices/infinity-ergodox/]. It functions just fine as a keyboard on my host computer, but when I try to bind it to the guest, nothing seems to happen. lsusb gives its ID: Bus 006 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub *Bus 005 Device 003: ID 1c11:b04d* Bus 005 Device 001: ID 1d6b:0002 Linux

running centos 6... have had a KVM linux vm (also C6) going for quite awhile that depends on a USB device mapping (a external audio DAC module). I updated the host today (yum update), it had been awhile (was like 6.5 before, now its 6.8+), and rebooted. the VM won't restart. when I try and restart it, I get this Error restoring domain: internal error Did not find USB device 8bb:2704

Dear all, I have a custom fact, that reads a file and then generate the values dynamically based on the file content. It''s something like this: inFile = "/home/admin/OSs.txt" > gos = {} > > if File.exist?(inFile) > open(inFile, ''r'').each do |line| > next if line =~ /^\s*(#|$)/ > parts =

That usually means that the VM kernel doesn't see that the device is

Dear All, maybe this is something obvious, I seem to be incapable of understanding how S4 works. So, in package 'A' I defined a "summary" method for my class: setMethod("summary", signature(object="ListHyperGResult"), function(object, pvalue=pvalueCutoff(object), categorySize=NULL) { "whatever" })

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?

So, if I remove the hostdev element related to the USB device, running `lsusb` and `usb-devices` inside the container lists the proper device, but I do not see the appropriate character device bus for the Android device under /dev/bus/usb. We are not entirely sure that `lsusb` and `usb-devices` queries the appropriate location - it somehow gets information from the host, not the guest container,

Hello,my system info: virsh verison Compiled against library: libvirt 3.9.0 Using library: libvirt 3.9.0 Using API: QEMU 3.9.0 Running hypervisor: QEMU 2.10.90 And i want to pass through my gpu to my window 7 guest with <hostdev>, next line is comand i use: <hostdev mode='subsystem' type='pci' managed='yes' xvga='yes'>

I am completely new to Linux and Wine. I've tried to make Wine work since some 1999, but never had patience with it. Tried reading guides, manuals and so on, but things did not work. All Linux versions I've tried have never run any windows-based programs after I installed Wine (and used to install a propper version of wine - that corresponds to Linux version) - what I did is what is said

OOPS: "If I do not want to disable the cgroup in container" ==> "If I do want to disable the cgroup in container" I meant if the user namespace not enabled in kernel ... thx ,I will try user namespace later. I am not working on x86 and not suer wheather the usernamespace is ok in the kernel I am going to use. I would try to disable the cgroup in lxc first.

Good day all I got my voicemail message working,thanks but now,keep in mind I'm using SIP We have,for example 4 people in our admin department.Each user has its own voicemail so that when their extension is dialed directly and not answered it gos to voicemail. But there is also a option to dial 3 for admin with will dial all 4 number in sequence.This I got working 100% but now I want a

Yes, I can use guest with this way, But when i hot-add my graphics card , Guest will reboot. So i want to try it with <hostdev>. Somehow , If i use "hostdev" without xvga , my screen will be black. If we have no hostdev, do you have other methods can help me to use hot-plug my graphics card? At 2018-01-04 23:27:52, "Laine Stump" <laine@redhat.com> wrote:

Dear Fil, I am not sure if my answer can help you. I had ever asked a similar question to Daniel and I was using a thirty-party card. As a container uses a shared kernel with the host, so hostdev mode='subsystem' doesn't make sense. Maybe you can try to use hostdev mode='capabilities'. Please see http://libvirt.org/formatdomain.html#elementsHostDevCaps Hope this helps Cheng

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.
