Virtual Machine Install
John T. Rine
The objective of this project is to successfully install a virtual machine on the Xen VM server.
To do this project, you will need to have successfully completed:
You will need:
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:
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).
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 General Information -------------------- Hostname : vm03 Distribution : squeeze Mirror : http://mirror/debian/ Partitions : swap 128Mb (swap) / 2Gb (ext3) Image type : sparse Memory size : 128Mb Networking Information ---------------------- IP Address : DHCP [MAC: 00:16:3E:2E:C0:03] Netmask : 255.255.255.0 Gateway : 10.80.3.1 Creating partition image: /xen/domains/vm03/swap.img Done Creating swap on /xen/domains/vm03/swap.img Done Creating partition image: /xen/domains/vm03/disk.img Done Creating ext3 filesystem on /xen/domains/vm03/disk.img Done Installation method: debootstrap Running hooks Done Role: udev File: /etc/xen-tools/role.d/udev Role script completed. Creating Xen configuration file Done Setting up root password
At this point, I was prompted to enter and then re-enter a passsword, which I performed.
Enter new UNIX password: Retype new UNIX password: Sorry, passwords do not match passwd: Authentication token manipulation error passwd: password unchanged All done Logfile produced at: /var/log/xen-tools/vm03.log Installation Summary --------------------- Hostname : vm03 Distribution : squeeze IP-Address(es) : dynamic RSA Fingerprint : 97:f7:8d:7a:45:2b:74:77:02:e2:dd:3a:d2:55:e3:0b 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.
root@vmserver04:~# cd /xen root@vmserver04:/xen# ls conf domains root@vmserver04:/xen# cd domains root@vmserver04:/xen/domains# ls vm03 root@vmserver04:/xen/domains# cd vm03 root@vmserver04:/xen/domains/vm03# ls disk.img swap.img root@vmserver04:/xen/domains/vm03# mount disk.img mount: can't find disk.img in /etc/fstab or /etc/mtab root@vmserver04:/xen/domains/vm03# mount -o loop disk.img /mnt root@vmserver04:/xen/domains/vm03# cd /mnt root@vmserver04:/mnt# ls bin dev home lib media opt root selinux sys usr vmlinuz boot etc initrd.img lost+found mnt proc sbin srv tmp var root@vmserver04:/mnt# chroot /mnt root@vmserver04:/# passwd Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully root@vmserver04:/# exit exit root@vmserver04:/mnt# cd root@vmserver04:~# 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???
