NAME OpenVZ - Base class for OpenVZ utilities like vzctl VERSION This document describes v0.01 of OpenVZ - released April 17, 2012 as part of OpenVZ. SYNOPSIS use parent 'OpenVZ'; #XXX: need to add more examples DESCRIPTION This is a base class for OpenVZ utilities like vzctl and vzlist. It shouldn't be used generally outside of this framework. FUNCTIONS new If you prefer an object oriented interface then just "use OpenVZ::submodule" and call the new function. All of the following functions will be available as methods. $vzctl = OpenVZ::vzctl->new; $vzctl->set({ ctid => 101, name => 'user101', save => '' }); execute This function should not be called directly unless you know what you're doing. "execute" uses IPC::Run3::Simple's "run3" function to make system calls. "run3" returns whatever is sent to STDOUT, STDERR and the exit value as well as the execution time of the system call. This function is the workhorse of this package. It expects the following parameters as a hashref command => program name to be called (e.g., vzctl) (STRING) params => parameters to be passed to the command to be called (ARRAYREF) "params" is optional. The params value will not be checked for validity. It is assumed that if you are calling this subroutine you have already validated whatever is going to be passed on the command line.
