Hi Guys, Recently, I'm doing some tests on openstack with lxc virtualization supported by libvirt. I need some recently new documents about libvirt lxc. Anything related is just ok. Thanks! -------------- Best regards! GuanQiang 2013-07-23

Hi there, I'm interested in using libvirt-lxc on armv7l architecture and I have a hard time building libvirt. 1. Are there any prebuild rpms for ARM? 2. I have many dependency issues during build: error: *** Error Summary *** === the following packages failed to build due to missing build dependencies === libvirt: nothing provides hal-devel nothing provides

Hi, I'm trying to build an active/active virtualization cluster using a Ceph RBD as backing for each libvirt-managed LXC. I know live migration for LXC isn't yet possible, but I'd like to build my infrastructure as if it were. That is, I would like to be sure proper locking is in place for live migrations to someday take place. In other words, I'm building things as if I were

Hello, I created lxc container on F19 with virt-manager and it starts OK. The only problem is that sshd does not run complaining "/dev/null is not a character device". # ls -l /dev/null -rw-r--r-- 1 root root 0 2014-02-25 22:39 /dev/null /sys/fs/cgroup/devices/machine/VM_NAME.libvirt-lxc/devices.list has "c 1:3 rwm" line, but I cannot create /dev/null: # mknod /dev/nulll c 1

Hi there! 1. Is it possible to build libvirt-lxc driver without building libvirt? How do I do it? 2. Do I understand it correctly, that I can use libvirt-lxc as a substitute of lxc? Thanks, Jan

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! I'd like to set up my first lxc container using libvirt. I'd like to start using the simplest configuration and next add things I need. So I've got xml as below: <domain type='lxc'> <name>vm1</name> <memory>32768</memory> <os> <type>exe</type> <init>/init</init> </os>

Hello, I'm using libvirt to build/run LXC instances. My LXC instances use passthrough filesystem mounts. When I try to do large file systems operations (ex tar or rsync) the file systems cache on the host spikes and causes the OOM handler to run and kills processes in the LXC. Has anyone else seen this? Is there a way around this? At this point I'm resorting to running a cron job that

Hi there I’m not quite proficient with libvirt yet, and have been using it so far primarily to manage lxc containers I was hoping to find a means to configure the set of capabilities that guests should drop, but came across a few web pages suggesting these were set in stone in the code is this correct, or is there a means to tweak this set from the host via the xml config or a virsh command ?

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

When I try to mount loop device in a linux container, I got the following error message: mount: Could not find any loop device. Maybe this kernel does not know about the loop device? (If so, recompile or `modprobe loop'.) I wonder how to enable mount loop device in LXC using libvirt LXC driver? -- Thanks! Du Jun

Hello, I'm seeing syslog messages "bleed" from the host and other LXC into the messages, maillog, secure logs of other LXCs. I'm using libvirt 1.0.0 on a host with systemd and kernel 3.9.10. Each LXC is running an older non-systemd linux distribution Is this a known issue? Is there a work around? Thank you for you time, Jim -- James R. Leu | Director of Technology | INOC

Folks, I found this thread <https://www.redhat.com/archives/libvirt-users/2015-August/msg00026.html>that talks about deprecating libvirt-lxc packages [1] [2] [3] in RHEL7.1. I am using [1] as a dependency for my application deployed on RHEL7.2 servers. For now it works fine but I am not sure about the future RHEL releases. The plan of deprecation was delayed or cancelled? Can someone

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

Dear all, I'm moving my first baby steps with libvirt-lxc trying to convert over from an LXD installation and one of the hurdles is putting together an image. All the examples I found about libvirt-lxc refer to running /bin/sh in a container, almost as if it was docker, as opposed to run a "full system" like I've been doing with lxd. Also virt-install, often referred in libvirt

Hi there! I am trying to turn on user namespace by adding following lines to the config: <idmap> <uid start='0' target='0' count='100000'/> <gid start='0' target='0' count='100000'/> </idmap> As you can see the root in container is mapped to the root outside. I was expected to see no difference

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
