Hi, I have a question concerning the practical use of lxc containers. Currently we have lots of complete virtual machines (kvm and xen) for services like fileserver/samba, dhcp/cups, ldap/kerberos, terminalserver, computecluster, etc. on about 10 hardware machines (mostly recent 2-socket quadcores). This serves about 60 concurrent users in our research institute.
As hardware gets more and more powerful, I would like to reduce the number of virtual machines (to make my life easier :^). Currently we reach the state to provide most of the services for the users like file- and terminalservices on *one* hardware machine (2-socket sixcore with X5680 CPU @ 3.33GHz), apart from any redundancy. My plan is to create really tiny containers to separate the services, and concentrate most of then on one machine. In a test container, I readonly bind-mounted the directories /usr /bin /sbin /lib /lib32 /var/lib/dpkg into lxc which leads to about 200MB size of the remaining lxc-tree. The problem appeared, that this does not work out of the box. Simple programs like atd don't work as e.g. the directories /var/spool/cron/atjobs/ and /var/spool/cron/atspool/ do not exist, just as /etc/init.d/atd. They have been created on the host during installation. This is just a simple example, but in general, most of the programs in /usr, /bin, etc. have configurations in /etc and leave traces in /var during installation. Does anybody use such an appealing setup and how can one handle this problem?
