Re: LXC template
Thank you Francois for the information. Please could you tell me which cloudstack template to use for spawning systems VMS on a LXC to spawn containers. I used LXC template found in database which was very old | 10 | SystemVM Template (LXC) | http://download.cloud.com/templates/acton/acton-systemvm-02062012.qcow2.bz2| SYSTEM | LXC | which did not work as cloudstack release was too old, then I tried with | 3 | SystemVM Template (KVM) | http://download.cloud.com/templates/4.2/systemvmtemplate-2013-06-12-master-kvm.qcow2.bz2| SYSTEM | KVM. Still my system VMs were rebooting only 1 VM is up at a time.

Re: LXC template
You need a real hypervisor to run your SSVM and CPVM (ie. KVM, Xen, etc.) You can't run the SSVM only on LXC.
