Help using XEN in CentOS 5.9

Hey guys, I've been straddling with this issue for quite some time now and I'm getting absolutely nowhere with it. It took me a long time to get XEN up and running on my server. We only use SSH to manipulate our servers, but we finally got it up and running. Now I'm at the point of actually attempting to create the servers. But my problem is, there doesn't seem to be any good documentation out there with a step by step guide on setting up Virtual Servers using XEN on CentOS 5.9, I can find various bits and bobs, but nothing solid to go on. I feel like I'm just guessing half of the time.

I'm trying to create VPS's with CentOS installed on them and some default folders etc. but I don't know how to create the initial image and then how to use it. I attempted to create the image using 'xen-image-create' with various parameters. The VPS sets up and the domain is listed, but I can't connect to it, which leads me to believe that the image is not working correctly. I just really need somebody to go over the steps for me, it'd be a great help and I'd really appreciate it, I'm trying to set up a hosting company with my friend, and we're trying to do it properly rather than using CGroup's and all of that terrible stuff to create servers. We want, full dedicated VPS's for our clients, we want to be a very permium hosting company, obviously we need to learn more, but there doesn't seem to be many companies out there that are willing to do that.

Back to my original topic, if somebody could just go over all of the steps to create a XEN VPS then that would be really really helpful. Before we were using the 'xm' command to create and administrate the servers, I assume this is Xen Management.

If you need any documents then I will provide, just not sure which documents you'll need to know about. Also our dedicated server is running CentOS 5.9 and we are trying to install CentOS onto the VPS's.

Thanks a lot guys, really appreciate this.

dtc_setup_vps_disk

dtc_setup_vps_disks(8)					      System Manager's Manual					    dtc_setup_vps_disks(8)

NAME

       dtc_setup_disk - setup LVM disks for using it as a VM

SYNOPSIS

       dtc_setup_vps_disk.sh VPS_NUMBER HDD_SIZE SWAP_SIZE [ lvm|loopback ]

DESCRIPTION

       dtc_setup_vps_disk.sh 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 create partitions to be used by a VPS later on.  It will create a normal partition that will be used as a root disk,
       and a swap partition.

       dtc_setup_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.

       If the partition(s) exists, then this script will delete it/them first.

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.

       HDD_SIZE Size in MB of the VPS partition to create.

       SWAP_SIZE  Size in MB of the VPS swap partition to create. If the dtc-xen SOAP server is used to create the VPS, then it will create a swap
       partition of the exact same size as the memory.

       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 15360 256 lvm

       This will create 2 LVM partition to be used by the VPS named xen04, the first one being a root partition of 15 GB, and the second one being
       a swap partition of 256 MB.

VERSION

       This documentation describes dtc_setup_vps_disk version 0.3.15.	See http://www.gplhost.com/software-dtc-xen.html for updates.
