Apache/httpd is something which you would like to have contained. And now fedora provides a native way/mechanism to to so with virt-sandbox-service. With this, you can create a virtualized sanbox service and then connect/list/manage such with virsh.
We will be using LXC.
Basically its couple of commands and you have a contained service running.
# List all the containers virsh -c lxc:/// list # Create the sandbox, all default parameters. Will take dhcp address. virt-sandbox-service create -C --username amitag -u httpd.service httpd_conta # Create the container with static IP. virt-sandbox-service create -C --username amitag -u httpd.service -N \ address=192.168.122.11/24%192.168.122.255 httpd_conta#Enable and start the service. virt-sandbox-service start httpd_conta virt-sandbox-service enable httpd_conta#Delete the container if not required any more. virt-sandbox-service delete httpd_conta

First we will setup cgroup to limit cpu and memory usage, so here we go:
Add the configuration in /etc/cgconfig.conf
#------start cgconfig---------------- #new group group firefox { perm { task { #user your login id and group here, so that you can control this group uid = amitag; gid = amitag; } admin { # same as above, set to your login id and group. uid = amitag; gid = amitag; } } # set the limits for cpu.. by default there are 1024 shares of cpu with no other groups, # so share of 102 would be around 10% . cpu{ cpu.shares="102"; } # limit the cpus to be used to only 0-1 cpuset{ cpuset.cpus=0-1; cpuset.mems=0; } # limit the maximum memory to 700Mb. memory { memory.limit_in_bytes="700M"; memory.max_usage_in_bytes="0"; } } #------end cgconfig----------------
