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

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

How to start the linux container's network interface automatically
Dear all,
I failed to start the linux container's network interface automatically. I have to start it manually each time after the container finishes booting.
I know that in a native fedora, if we want the network interface to start automatically, we should edit "/etc/sysconfig/network-script/ifcfg-eth0 and add the string "ONBOOT=yes".
My host is fedora 16. I used "yum

Re: How can a user process be automatically started after the container is started?
Dear Daniel,
You said "use a real init system like systemd to spawn off the things", do you mean a full OS distro container?
I installed the container using "yum --installroot=/root/fedora19lxc --releasever=19 install -y openssh, bridge-utils" which is described at https://www.redhat.com/archives/libvirt-users/2013-August/msg00007.html.

a question on vCPU setting for lxc
Dear all,
I am not clear about the 'vcpu' element for CPU allocation. I allocated 1 vCPU to my container, after I started the container, I ran 4 computation-intensive tasks on the container. And I found all the 4 physical core are 100% used (my host has 4 physical cores and no other application ran on the host except the container). That is, all available cores were used by the container.

Docker container isolation not working in CentOS 7
Hi,
I've decided to use these summer holidays to wrap my head around Docker and its
quirks. Spent the last couple weeks working through a Udemy tutorial and a
thick book about Docker, and I have Docker CE installed on two machines:
* my workstation running OpenSUSE Leap 15.1
* a public sandbox server running CentOS 7
I'm currently fiddling with custom networks and container

Container setup?
Hi Patrick,
thanks for the pointers. I tried today, and while it was easy to start my first container, I am not really happy with LXD, exactly for the reason St?phane gives in

Getting IP address of a lxc container via libvirt
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

Re: a question on vCPU setting for lxc
Hi,
I'm not libvirt expect. My guess is that some vcpu settings only apply to
KVM/qemu backend. LXC is quite different from them.
If setting vcpu# is not effective for LXC container, you may need to use
cgroups.

How to pin an libvirt lxc to a specific physical CPU core in openstack?
Dear all,
In my applications, the real-time performance is very important, so I used 4 containers, with only one application running in each container and a physical CPU core is only dedicated to one lxc. and I must know which container is hosted by which CPU core. That is, I need to pin a specific lxc to a specific CPU core.
I can achieve this in a native linux system by the following xml

Container setup?
> * What are pros and cons of container vs. VMs?
Same as any other containerized setup. We've been running our Samba DCs
and file servers in nspawn containers (similar to LXC) for a couple of
years, no container-specific issues yet.
Though I'm not sure if docker is the right tool for the job; samba as a
fat daemon running a bazillion subprocesses orchestrated by a persistent

Re: method for communication between containers
Dear Daniel,
As you know, following your suggestion, I can expose shared memory to two containers hosted by the same machine, thus the two containers can exchange data. Now I have a new problem: how does the containers avoid concurrent accesses to the shared memory? In a native system, this can be achieved by using semaphore. But I don't know how the two containers can see the same semaphore.
