similar to: a question on vCPU setting for lxc

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 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, 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

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

Hi, I'm using libvirt/kvm with openstack. When vm has CPU stall, the instance can't be destroyed. I have asked the question on openstack user mailing list and received no answers in weeks. Here is one example: # virsh destroy instance-00000085 error: Failed to destroy domain instance-00000085 error: Failed to terminate process 61222 with SIGKILL: Device or resource busy

Dear all, I want my container to run on the third CPU core and I define this by the following xml scrpits: <vcpu placement="static" cpuset="3">1</vcpu> When I run my application in a container terminal, I can see the application runs on the third core as expected. When I run my application using lxc-enter-namespace, the CPU pinning doesn't take effect, i.e.,

Dear all I allocate only one vcpu for the container by the following statement, that is, I want to pin the vcpu to physical core "2". <vcpu placement='static' cpuset="2" >1</vcpu> My host has 4 physical cores. Before test, all the 4 cores are idle. After I run 4 processes in the container, I found all the 4 cores in the host are 100% used. That is, the

Hi folks! i created a server with this XML file: <domain type='lxc'> <name>lxctest1</name> <uuid>227bd347-dd1d-4bfd-81e1-01052e91ffe2</uuid> <metadata> <libosinfo:libosinfo xmlns:libosinfo="http://libosinfo.org/xmlns/libvirt/domain/1.0"> <libosinfo:os id="http://centos.org/centos/6.9"/>

Hi, We are using Openstack and Libvirt/LXC as our virtualization endpoint. Here is an example of one of our libvirt domain: http://paste.debian.net/167276/ So we have <vcpu>4</vcpu>. But the command : root at PAR-SRV-02-MASTER:/etc/libvirt/lxc# virsh --connect lxc:/// dominfo instance-0000004a Id: 17495 Name: instance-0000004a UUID:

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,

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

Hi, I seem to have a problem when creating a LXC container through virsh. While virsh -c lxc:/// dominfo <container> shows up (for example) 2 VCPUs as defined, if I run a CPU intensive task (such as stress --cpu 10) it will max out 10 CPU cores on the host. If I echo "0" > /cgroup/cpuset/libvirt/lxc/<domain>/cpuset.cpus then the container is properly confined to just

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.

Dear all, I want to have a view of lxc CPU usage in openstack Dashboard. According the Openstack official site , Openstack Ceilometer can poll libvirt daemon to obtain CPU usage of a virtual machine. I tried the command locally on the libvirtd host "virsh -c lxc:/// domjobinfo", I got an error "error: this function is not supported by the connection driver:

Dear all, I use virsh command to start a container and connect to it. When I use virsh -c lxc:/// console mycontainer, I only have one console. I wonder how to open multiple terminal windows for the same container. Thank you in advance Cheng Wang
