How to reclaim the space which i used to increse the swap space on Xen,

Hi,
i have done a blunder here, i increased the swap space on Xen5.6 server machine using below steps :-
HTML Code:
1056  dd if=/dev/zero of=/root/myswapfile bs=1M count=1024
 1057  ls -l /root/myswapfile
 1058  chmod 600 /root/myswapfile
 1059  mkswap /root/myswapfile
 1060  swapon /root/myswapfile
but it has used all the space on /root and hence to recover the space on /root i removed /root/myswapfile using rm -rf. But still i see the space is full and swapon give below output:-

Filename Type Size Used Priority
/root/myswapfile\040(deleted) file 968764 0 -1

Can any help me here please, how to resolve this and get my system to previous state?

Thanks in advance....

NAME
dtc_kill_vps_disk - destroy LVM disks for freeing space SYNOPSIS
dtc_kill_vps_disk VPS_NUMBER [ lvm|loopback ] DESCRIPTION
dtc_kill_vps_disk This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server. This script is used to delete a partitions that was used by a VPS. It will delete the normal partition that was used as a root disk, and the swap partition. dtc_kill_vps_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool. OPTIONS
VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group called lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap. IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then this script will create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS. EXAMPLE
dtc_setup_vps_disk 04 lvm This will delete the 2 LVM partitions that were used by the VPS named xen04, the first one being the root partition, and the second one being the swap partition. VERSION
This documentation describes dtc_kill_vps_disk See http://www.gplhost.com/software-dtc-xen.html for updates. SEE ALSO
