Networking issues with lxc containers in AWS EC2
I've created an EC2 AMI for AWS that essentially represents a CentOS 7 "hypervisor" image. I deploy instances of these in AWS and create an number of libvirt based lxc containers on each of these instances. The containers run fine within a single host and have no problem communicating with themselves as well as with their host, and vice versa. However, containers hosted in one

Mapping physical interface to a container
In the "other" LXC project (linuxcontainers.org), you can map a host's physical ethernet interface to a container, e.g. lxc.network.type = phys lxc.network.flags = up lxc.network.link = eth1 lxc.network.name = eth1 Is there an equivalent option for doing this with libvirt lxc? Peter

libvirt-lxc
Hi, I noticed that libvirt-lxc will be deprecated for RedHat: "Future development on the Linux containers framework is now based on the docker command-line interface. libvirt-lxc tooling may be removed in a future release of Red Hat Enterprise Linux (including Red Hat Enterprise Linux 7) and should not be relied upon for developing custom container management applications." -

Installation of libvirt on Ubuntu
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

Setting environment variables for LXC Containers
Hello Is there a way to set custom environment variables for LXC containers so that it is available for all processes within the container? The libvirt-lxc driver seems to be setting up only the below variables (as per the docs), but there doesn't seem to be a way customize it. containerThe fixed string libvirt-lxc to identify libvirt as the creator container_uuidThe UUID assigned to the

[OT?] VM or Container for an AD DC?
I'm starting to deploy my new domain in my organization, setting up the new domain and DCs. I'm following the recommendation to create the DCs as ''DC only'', eg with only samba and a root access for ssh. Having to choose between VMs and Containers (LXC), there's differences between them that can involve samba features/performances? Filesystem limitation? Seems to
