LinuxQuestions.org - Allocating resources to VPS's using OpenVZ

I need a layman's term definition of these parameters and what they do in terms of allocating resources to servers, as I'm having issues with the VPS's that I set up, as Java seems to be unable to set up a virtual machine on them for minecraft unless they have over 2Gb's of each parameter, and I'm assuming I must be doing something wrong. Here is the current script exert that I use to initially create the server and assign resources:
Code:
    SERVID=$1

    IPPICK=$2

    HOSTNAME=$3

    PW=$4

    EMAIL=$5

    

    if vzctl create $SERVID --ostemplate centos-6-x86_64.2 --config vps.packtwo-basic ;

            then

                    echo -e "\nVPS container was successfully created...\n"

            else

                    vzctl stop $SERVID

                    vzctl destroy $SERVID

                    echo -e "Please restart the package install, there was a problem creating the VPS..."

                    exit $?

    fi

    if vzctl set $SERVID --onboot yes --save;

            then

                    echo -e "\nSet to boot on start...\n"

            else

                    vzctl stop $SERVID

                    vzctl destroy $SERVID

                    echo -e "\nPlease restart the package install, the onboot config went wrong...\n"

                    exit $?

    fi

    

    if vzctl set $SERVID --ipadd $IPPICK --save;

            then

                    echo -e "\nIP added to the VPS successfully...\n"

            else

                    echo -e "\nThe IP address used, may be used on another server, this may mean that the server has an issue contacting external addresses..\n"
