similar to: Libvirt LXC hostname

Hi all, I am trying to bring up lxc's using Libvirt JAVA API. I do the following: conn = Connect("lxc:\\\") xml_config = "<domain> .... <\domain>" dom = conn.domainCreateXML(xml_config, 0) dom.create() Using the above code, I am able to start a domain but the domain is not visible within the "lxc" list, i.e when I use the command "lxc-ls

Hi all, I have installed a CentOS6 lxc guest under a Debian 8.x LXC host. All it is working ok but I can't change the hostname for the centos6 lxc container (it is using the same hostname from Debian host). I have modifyed HOSTNAME under /etc/sysconfig/network and /etc/hosts file, but it doesn't works. Do I need to change anything else?? Thanks.

Hi everyone, I've some doubts regarding the usage/working of libvirt-lxc with openstack. I'm doing a project titled "Low density virtualization for Storage cloud" 1. Can i use libvirt for lxc with Openstack swift alone (excluding nova, glance and keystone)? If no what other openstack components should i use for virtualization? (Is it necessary to install openstack nova to do

Hi folks I have a question about lxc-enter-namespace I am migrating lxc containers from a host running libvirt-1.2.5 on f20 to another one running libvirt-1.2.9 on f21 and now I can't seem to use lxc-enter-namespace for entering in a container any more I would do virsh -c lxc:/// lxc-enter-namespace --noseclabel container /bin/bash but when I try the same now I am getting this: # virsh

Hi, Has anyone used libvirt to start/stop/manage LXC (linux containers) ? Is it supported at all? Last I tried, had few issues and the reply was : /// Note that libvirt lxc driver is a different implementation from lxc tools and doesn't use lxc tools internally. You may not be able to do what you are doing with lxc tools. Especially, the driver doesn't take aware of files and settings

Hi, i converted LXC conf to xml by: lxcuser@blade1:~/.local/share/lxc/test_deb$ virsh -c lxc:/// domxml-from- native lxc-tools /home/lxcuser/.local/share/lxc/test_deb/config <domain type='lxc'> <name>test_deb</name> <uuid>cce77799-89fd-41fd-99c1-101e00844e23</uuid> <memory unit='KiB'>65536</memory> <currentMemory

Hi, all, I used lxc-tools to create a linux container. I am trying to transfrom LXC container configuration into a domain XML fragment using the following command: *$ virsh -c lxc:/// domxml-from-native lxc /var/lib/lxc/my_conatiner/config* However, I get the error message, error: this function is not supported by the connection driver: virConnectDomainXMLFromNative It seems that

Hello, I would like to set up sshd under an LXC application container and to be able to connect into it from the host. I was able to achieve that with LXC tools CLI after setting up a bridge via brctl and creating a proper lxc.conf file for lxc-execute to use. However, I am unable to do so via libvirt. I am using libvirt version 0.7.1 installed on fedora 12. I first verified that the default

Hi Guys, When I created a lxc container by libvirt, I logged into the lxc container and noticed that info under /proc/ dir did not match the lxc container resource. Is the /proc dir in lxc container just showing the same thing as the lxc host? If I want to monitor the realtime resource usage inside the lxc container, What should I do? -------------- Best regards! GuanQiang 2013-07-23

Dear all, I'm a happy lxc (lxd) user with a need to add a bunch of KVM images to the mix. More importantly I need to have some simple frontend to give users the ability to quickly run some VMs for testing. Researching the topic brought me to virt-manager and from there libvirt. I've had however a hard time to answer a few questions that I hope this list can help me with: 1) is the

Hi experts, When I hotplug nic into lxc, the nic in lxc seemed to be down status as following: 1224: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether fa:16:3e:fc:e5:96 brd ff:ff:ff:ff:ff:ff It seems mechanism such as udev is needed here. But I found udev is not supported well in lxc. So how can I get a 'up' nic after hotplug into lxc ? Very

Hi there, I'm fairly new to libvirt and LXC, please forgive my ignorance. I was looking for a graphical tool to manage LXC containers and noticed that libvirt has support for LXC. Actually, I expected libvirt to be able to display and manage LXC hosts much like KVM. But it does not happen this way. The only thing I can see with virsh/virt-manager is storage pool with LXC containers, but not

Hello The latest attempts that I made on fedora21 all gave me the same result I have tried . vanilla rpm from f21 (1.2.9 IIRC) . 1.2.14 . 1.2.13 . 1.2.12 these three ones I rebuilt from the source rpm published by libvirt eventually I reworked my own tools to enter the container via ssh, so this is not an immediate concern to me any longer but it is definitely odd I currently use 1.2.12

Hello, I am searching for the libvirt operations for relocating LXC (system or application) containers. LXC relocation mechanism is done by checkpoint / restart. I went over libvirt API documentation and found the following methods: virDomainSave that receives a domain and path to state file. The method saves domain's memory contents into a disk file. virDomainRestore that receives a domain

Hi, I've been making some tests with libvirt and LXC and found some problems when halting/restarting a LXC container from within. Basically, on a Ubuntu 12.04 system with libvirt installed as package (0.9.8), I've created a basic container image with: lxc-create -t ubuntu -n lxc And started it using the libvirt XML listed below and the following command: virsh -c lxc:// create

Hello I wanted to understand if there is a way to get LXC container's ip address. - virDomainInterfaceAddresses API only works for qemu/kvm and not with the lxc driver. What other options do I have? Using enter-lxc-namespace is throwing this error: virsh -c lxc:/// lxc-enter-namespace <domain> --noseclabel /sbin/ifconfig libvirt: error : Expected at least one file descriptor

Hi experts, When I test lxc-enter-namespace interface, it turned out such an error: hzguanqiang@debian:~$ vir version Compiled against library: libvirt 1.1.4 Using library: libvirt 1.1.4 Using API: LXC 1.1.4 Running hypervisor: LXC 3.9.6 hzguanqiang@debian:~$ vir list Id Name State ---------------------------------------------------- 1544 instance-00000015

I'm trying to permanently change memory allocation for a libvirt-lxc domain. So far I tried changing memory in memory.limit_in_bytes under /cgroup/memory/libvirt/lxc/<container>/.  This didn't help. It appears that libvirt is not reading changes in cgroup. My requirements are 1) Be able to dynamically change memory of a LXC domain without reboot 2) The memory change must survive

Hi folks I use libvirt to programmatically spawn lxc containers I am facing an issue when migrating from fedora23 to fedora24 I use the stock kernel and libvirt version on both deployments, i.e.: f23: libvirt-1.2.18.3-2.fc23.x86_64 - kernel 4.5.7-202.fc23.x86_64 f24: libvirt-1.3.3.1-4.fc24.x86_64 - kernel 4.6.3-300.fc24.x86_64 First off, I need to outline that the host installation is done
