similar to: LXC guest to have/make a device node (FUSE)

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

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

Hi. I need to use /dev/ppp inside the lxc container, for very ancient software. Problem solved this way: 1) virsh edit container name and add section: <features> <capabilities policy='default'> <mknod state='on'/> </capabilities> </features> 2) start container 3) attach or ssh container, be root: #mknod /dev/ppp c 108 0 4) inside

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 want to run a VPN software inside an lxc guest, but the required TUN/TAP device (/dev/net/tun) is missing in the container. Anyone knows how to enable this device ? Here is the definition XML: <domain type="lxc"> <name>centos</name> <memory unit="MiB">1024</memory> <os> <type>exe</type>

Dear Daniel, The thirty-party PCIe card is based on the Xilinx’ FPGA which is off the shelf, the main features are as follows: 1) x8 Gen3, 8Gb/s per lane/direction 2) MSI and legacy interrupt support 3) Scatter-gather packet DMA engine provide by Northwest Logic We hope multiple Linux Containers to access the PCIe card in time division mode, for example, during slot 1, lxc1 read/write the PCIe

Dear Daniel, I found that lxc driver doesn't support hostdev with type of 'pci'. As you mentioned before, I tried to expose the device node (the PCIe card) to the container, my XML is as follow: <devices> <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address bus='0x01' slot='0x00'

Hi, I created an LXC domain via libvirt (on Fedora 20), but when I'm trying to mount a FUSE filesystem, like sshfs, I'm getting a following error: $ sshfs 172.30.15.2:/<mntdir> /<mntpoint> fuse: device not found, try 'modprobe fuse' first I see that there's no /dev/fuse device. Is there a way to make it work? Can I get it working via libvirt domain xml file

Dear all, There are two containers hosted by my host machine. And the host machine has two same 1G NICs. I want to assign a dedicated NIC to one container. The host and the other container share the second NIC. How can I achieve this? Any comments will be highly appreciated. Cheng

Hello. Centos 7.6 with libvirt build from base "virt" repository: libvirt-daemon-driver-lxc-5.0.0-1.el7.x86_64 libvirt-client-5.0.0-1.el7.x86_64 libvirt-daemon-5.0.0-1.el7.x86_64 libvirt-daemon-driver-network-5.0.0-1.el7.x86_64 libvirt-libs-5.0.0-1.el7.x86_64 + systemd-219-62.el7_6.2.x86_64 Now lxc containers with type='direct' can be started, but can't be stopped :)

Hi all I have CentOS Linux release 7.0.1406, libvirt 1.2.7 installed. Just after create and start inside LXC container present cgroups.

Hi all, I am not able to access USB as storage device in the lxc container. Having tried to pass the usb device with the product and vendor id, not able to see the device mounted in the lxc file system. However, they are seen as char devices in the container at the location. There is no issue of ACL, as the capabilities restrictions have been dropped. Has anyone successfully mounted the storage

Hi! First post, kind of a noobie. I've been working with LXC and libvirt for a few months now. Trying to do some interesting things with containers and Android devices :D I'm running ubuntu 13.10 with LXC 1.0.1 and tried both libvirt 1.1.1 and 1.2.2 (backported from ubuntu-trusty), but with either version of libvirt am getting issues as soon as I try to get access to USB devices inside

Yeah, AppArmor is enabled, but I put everything (that I could find) into complain mode: $ sudo apparmor_status apparmor module is loaded. 12 profiles are loaded. 3 profiles are in enforce mode. lxc-container-default lxc-container-default-with-mounting lxc-container-default-with-nesting 9 profiles are in complain mode. /sbin/dhclient /usr/bin/lxc-start

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

Further followups! We are correlating DEBUG-level output from libvirt with the libvirt 1.2.2 code to try to figure out what libvirt is doing under the hood. Even though we have the log level set to 1 (info) in our libvirtd.conf, we are not seeing the VIR_DEBUG() [1] statements being printed out. There are tons of other presumably-debug lines of output showing up in our log. We are sort of
