[LXC][Openstack] Clarifications needed on usage of libvirt-lxc for openstack
Hi everyone,
I've some doubts regarding the usage/working of libvirt-lxc with openstack.
I'm doing a project titled "Low density virtualization for Storage cloud"
1. Can i use libvirt for lxc with Openstack swift alone (excluding nova,
glance and keystone)? If no what other openstack components should i use
for virtualization? (Is it necessary to install openstack nova to do

OpenStack+libvirt+lxc: lxcContainerGetSubtree:1199 : Failed to read /proc/mounts
Hi,
I'm running OpenStack on CentOS 6.3 to manage lxc instances. And running
into series of problem relating libvirt and lxc interaction.
For example, libvirt_lxc segfault (
https://bugzilla.redhat.com/show_bug.cgi?id=874549) which has an upstream
fix. And another bugs such as fail to start when SELinux disabled.
Finally, I decides to adopt libvirt 0.10.2, self compiled

libvirt with lxc: internal error The 'cpuacct', 'devices' & 'memory' cgroups controllers must be mounted
Hi,
I'm running OpenStack to manage LXC instance through libvirt. The same

dumped following message when starting lxc instance.

LXC and Dahdi
Howdy,
I am playing around with asterisk within an LXC container on Ubuntu 11.04.
I have asterisk (1.4.42) running fine, but want access to dahdi_dummy for
timing (meetme). I have dahdi installed on the "host", and dahdi_dummy is
loaded:

How to change libvirt / cgroup interaction?
Hi there,
Do you know if there is a way to modify how libvirt interacts with the
cgroup?
Because, I successfully add the /dev/net/tun support in my LXC container
by doing:
echo c 10:200 rwm >> /cgroup/libvirt/lxc/instance-00000005/devices.allow
But when I restart the instance/LXC container, this option has gone.
How can I make this persistant? Is there a configuration file?
Thanks

Libvirt "tc ingress qdisc" automatically removed by ovs vlan tag setting, how?
With outbound QoS setting in Libvirt XML, libvirt will add a tc
ingress qdisc for traffic shaping. Then if you set VLAN tag to that
tap device, this qdisc will automatically gone by no reason.
Could anyone shed some lights where should I look into? I'm really
confused and got no clue here. Thanks!
Steps to reproduce

libvirt lxc /dev/null
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".

How automatically set group.devices.allow for libvirt-lxc container after start ?
Hi.
I need to use /dev/ppp inside the lxc container, for very ancient software.
Problem solved this way:
1) virsh edit container name and add section:
<features>
<capabilities policy='default'>
<mknod state='on'/>
</capabilities>
</features>
2) start container
3) attach or ssh container, be root:
#mknod /dev/ppp c 108 0

using fuse with libguestfs
Upon seeing RWM Jones article "Using mount-local API from C" I became
curious because I thought there WAS a way to combine aspects of FUSE
with the tools provided by libguestfs. So if I wanted to create my own
filesystem using callbacks placed in the 'fuse_operations' struct
(parameter to 'fuse_main()'), I could do so using guestfs.
But after reading the article and
