add swappages description
in any container or the host system,
or failures of container starts.
 
Also, large <code>numiptent</code> cause considerable slowdown of processing
of network packets. It is not recommended to allow containers
to create more than 200–300 <code>numiptent</code>.
 
== swappages ==
 
The amount of swap space to show in container.
 
{{Note|this parameter is only available in RHEL5-based kernel since version 028stab060.2.}}
 
The configuration of this parameter doesn't affect security and
stability of the whole system or isolation between containers.
Its configuration only affects the way OpenVZ kernel reports about
available swap in a container. This is needed for some applications
which refuse to run inside a container unless the kernel
report that no less than some specific amount of swap is available.
 
If <code>limit</code> is set, its value is reported as the amount
of total swap space in a container.
 
If the <code>limit</code> is set to [[MAX_ULONG]] (which is the
in-kernel default for this parameter), all the swap space values
parameters (total, used, free) are reported as 0.
 
The value of <code>barrier</code> for this beancounter is ignored.
