Dear Ramaekers, Perhaps I didn’t describe the problem clearly. Libvirt has built-in driver for linux container, so, on Fedora, libvirt can be used to start and stop the linux container. (libvirt’s official website is libvirt.org). On Ubuntu, a user tool from https://linuxcontainers.org" is usually used to manage Ubuntu container. I noted that the use of the two user space tools are different. The problem is I can realize sharing memory between containers on Fedora which is very important for me. But I wonder if I use the tool from https://linuxcontainers.org to manage Ubuntu container, whether I also can share memory between Ubuntu containers?

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 lxc. (as you may know, there is another lxc user space tool on Ubuntu whose official website is "https://linuxcontainers.org", which I don't want to use). My questions are: 1) Can I install libvirt on Ubuntu with the same installation steps as on Fedora (i.e., manually download the tar.gz packet and install it locally)? I found a link talking about installation libvirt on Ubuntu which installs something like "libvirt-bin" (https://help.ubuntu.com/lts/serverguide/libvirt.html). I am not sure if libvirt can be installed following this instruction? 2) How can I create the rootfs for a Ubuntu container if libvirt can be installed on Ubuntu? I create the rootfs for Fedora container using: # yum --installroot=/root/fedora16linux container --releasever=19 install -y openssh, bridge-utils". How can I achieve this on Ubuntu? 3) If libvirt can work on Ubuntu, Can a disk file on the host OS be exposed to a Ubuntu container just like on Fedora? With my warmest regards, Cheng Wang
