libvirt users - Mar 2015 - Re: 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 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

Libvirt is in the standard repositories... Why don't you just install it
with ex tasksel?

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?
