similar to: How to assign multiple IP addresses to a container

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

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

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

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,

Dear all, I am not clear about the 'vcpu' element for CPU allocation. I allocated 1 vCPU to my container, after I started the container, I ran 4 computation-intensive tasks on the container. And I found all the 4 physical core are 100% used (my host has 4 physical cores and no other application ran on the host except the container). That is, all available cores were used by the container.

Dear Gene, Thank you for your response. I want to assign a static IP address to my container, I wonder if I can achieve this by editing the container's /etc/sysconfig/network-scripts/ifcfg-eth0. I tried this, but failed, and eth0 is always not assigned an IP address automatically (my host and guest are fedora19). Am I missing something? I don't know much about the booting procedure of a

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

Dear all, I wonder if libvirt can work on Ubuntu. As you know, it is very convenient to install libvirt on Fedora. I can download the libvirt packet from libvirt.org and install it using command ./configure, make and make install. As I am going to install an open source simulation system named openairinterface, Ubuntu is the recommended OS, and I want to install the simulation system in libvirt

Libvirt is in the standard repositories... Why don't you just install it with ex tasksel?

Hi, I'm not libvirt expect. My guess is that some vcpu settings only apply to KVM/qemu backend. LXC is quite different from them. If setting vcpu# is not effective for LXC container, you may need to use cgroups. -- Thanks, Yuanle On Mon, Mar 17, 2014 at 2:32 PM, WANG Cheng D < Cheng.d.Wang@alcatel-sbell.com.cn> wrote: > Dear all, > > I am not clear about the

Hi Chang Weng, Thanks for answering! Could you explain why subsystem=USB does not make sense? I was simply following the documentation for USB devices (right above the section you linked to). For what it's worth, I've also tried mounting the specific character device related to the appropriate android device into the container in the way you suggest, with no luck; `adb` still does not

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'

Dear Daniel, You said "use a real init system like systemd to spawn off the things", do you mean a full OS distro container? I installed the container using "yum --installroot=/root/fedora19lxc --releasever=19 install -y openssh, bridge-utils" which is described at https://www.redhat.com/archives/libvirt-users/2013-August/msg00007.html. I don't know how to make systemd

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 all, I want to run a TCP/IP application automatically after I start the container using "virsh -c lxc:/// start mycontainer". Does anybody know how to configure the NIC automatically with an assigned IP address? I couldn't find useful information from domain XML format spec and it only talks how to set the mac address (http://libvirt.org/formatdomain.html) . Your response will
