Objective

The objective of this project is to successfully install a virtual machine on the Xen VM server.

Materials/Reading/Prerequisites

To do this project, you will need to have successfully completed:

Linux VM Server Install

You will need:

an allocated VM that nobody else has claimed

Background

A virtual machine is an encapsulated piece of software which behaves just like a physical machine, a computer. It has its own virtual hardware, for example, a network interface card, a CPU, and RAM. It executes its own applications on its own operating system or systems. According to vmware.com, virtual machines have four key characteristics that make them attractive to a user:

Compatibility: (vmware) Virtual machines are compatible with all standard x86 processors
Isolation: All virtual machines are isolated from each other as if they were physically separate machines
Encapsulation: Virtual machines encapsulate an entire computing environment
Hardware independence: Virtual machines run independently of underlying hardware

From the instructor's project page:
Following your setup of a VM server, the next logical step is to do something with it; creating and running virtual machines allows you to have network-accessible machines that you can set up various services, just as if they were a real machine.

Host names: vm##.student.lab  (01-32)
MAC address: 00:16:3e:2e:c0:##

For vm01, ## would be "01"
For vm10, ## would be "0a" (they're in hex).
For vm32, ## would be "20" (0x20 = 32).

Procedure

The install begins…
First, from a remote computer, I logged into my VM server (xen) as the root.

wildgoat:~$ ssh root@vmserver04.student.lab
Warning: Permanently added 'vmserver04.student.lab,10.80.3.61' (RSA) to the list of known hosts.
root@vmserver04.student.lab's password: 
Linux vmserver04 2.6.32-5-xen-686 #1 SMP Wed Jan 12 07:52:18 UTC 2011 i686

The programs included with the Debian GNU/Linux system are free software;
the exact distribution terms for each program are described in the
individual files in /usr/share/doc/*/copyright.

Next, I performed an xm list to determine whether or not there were virtual machines already running.

As can be seen above, there were no virtual machines running on my VM server, so the next step is to create one. Actually, I installed two, these instructions reflect the steps taken during the first install. Before the virtual machine can be created, however, the installer must choose open (unused) virtual machines. The machines are listed on the hpc0 notes page: http://lab46.corning-cc.edu/notes:hpc0 .
I chose the following open machines:

Hostname	VM Server	MAC Address	Owner
vm03	vmserver04	00:16:3E:2E:C0:03	John Rine
vm04	vmserver04	00:16:3E:2E:C0:04	John Rine

After claiming virtual machines, the next step is to execute the xen-create to create a virtual machine.

root@vmserver04:~# vmserver:~# xen-create-image --hostname=vm03 --mac=00:16:3e:2e:c0:## --role=udev
-bash: vmserver:~#: command not found

I copied and pasted the xen create command from the hpc0 VM install project page. Next, I substituted “–hostname=vm##” with “–hostname=vm03” and the MAC address, “–mac=00:16:3e:2e:c0:” with “–mac=00:16:3e:2e:c0:”.
After executing the command, I received an “command not found” message. The command wasn't found because when I copied and pasted the command from the VM install page, I didn't remove the double '#' string immediately following the MAC address.

root@vmserver04:~# --mac=00:16:3e:2e:c0:## --role=udev
-bash: --mac=00:16:3e:2e:c0:##: command not found

After fixing the xen-create command line options, I executed the xen-create command.

root@vmserver04:~# xen-create-image --hostname=vm03 --mac=00:16:3E:2E:C0:03 --role=udev
  The output directory for creating the xen configuration file within
 doesn't exist:

           /xen/conf

  Aborting.

Since the /xen/conf directory, didn't exist, I created it.

root@vmserver04:~# cd /
root@vmserver04:/# mkdir xen
root@vmserver04:/# cd xen
root@vmserver04:/xen# mkdir conf
root@vmserver04:/xen# cd ~

After creating the /xen/conf directory, I executed the xen-create command again.

root@vmserver04:~# xen-create-image --hostname=vm03 --mac=00:16:3E:2E:C0:03 --role=udev

At this point, I was prompted to enter and then re-enter a passsword, which I performed.

Enter new UNIX password:

Root Password   :  N/A

As can be seen above, I didn't enter passwords that matched, but the install finished anyway! I was forced to re-enter the password. I order to do that, I had to find the disk image, mount it with “loop” in /mnt, change the root using /mnt, change the password, and then unmount (umount) /mnt.

The next step was to boot the virtual machine using xm create -c /xen/conf/vm##.cfg. I copied this line from the hpc0 VM install project page and replaced the double '#' string with my virtual machine designator 03, and then executed the command.

root@vmserver04:~# vmserver:~# xm create -c /xen/conf/vm03.cfg
-bash: vmserver:~#: command not found

Oops, When I copied and pasted the line from the instructions, I didn't remove the command line stuff. I pasted it again, but this time I removed the command line propt that was part of the example. I didn't, however, replace the double '#' string with my virtual machine designator, 03, but it apparently finished okay-why???

root@vmserver04:~# xm create -c /xen/conf/vm##.cfg
Error: Unable to open config file: /xen/conf/vm##.cfg

                     Use the given Python configuration script.The
                     configuration script is loaded after arguments have
                     been processed. Each command-line option sets a
                     configuration variable named after its long option
                     name, and these variables are placed in the
                     environment of the script before it is loaded.
                     Variables for options that may be repeated have list
                     values. Other variables can be set using VAR=VAL on
                     the command line. After the script is loaded, option
