Following your set up of a VM Server, log into the VM server as root using the command 'ssh root@vmserver02.student.lab' and the root password you created at set-up.

Once you have access to the VM Server:

• Check the number of running virtual machines using the 'xm list' command.
• If there are more than 8 virtual machines running, use a different VM Server.

Now go to a separate web-browser window to choose your virtual machine hostname.

• Look at the chart located under “VM Server User Lists” on the HPC Fundamentals Notes page.
  • Claim an open VM by editing the table.
    • Enter the name of the VM server you are using in the second column of the table for the appropriate virtual machine.
    • Enter your name in the last column of the appropriate virtual machine.
    • Note the MAC addresses of the virtual machine you've claimed on the chart (You will use it shortly.)

Returning to the terminal window, which is logged into the VM Serrver you're going to use.

• While inserting the hostname and MAC address noted from the chart on HPC Fundamentals Notes page.
  • Use the command 'xen-create-image –hostname=vm## –mac=##:##:##:##:##:## –role=udev'
    • For example, vm24's command would be 'xen-create-image –hostname=vm24 –mac=00:16:3E:2E:C0:18 –role=udev'
      • The number in the hostname is in decimal.
      • The number in the MAC address is in Hexidecimal.
  • If you have no errors in /etc/xen/xend-config.sxp or /etc/xen-tools/xen-tools.conf it should proceed.
    • Watch for warnings!

If your Virtual Machine was created successfully you can now 'boot' it. When you are ready to boot your virtual machine use the following command:

root@vmserver##:~# xm create -c /xen/conf/vm##.cfg

• Where ## is the number of the virtual machine you created in the creation section.
  • To boot the vm without viewing it use the following command:

root@vmserver##:~# xm create /xen/conf/vm##.cfg

• When the virtual machine has finished booting you can detach from the virtual machine, returning to the VMServer prompt, using the <Ctrl>+<]> command.

You can now access your virtual machine from any lab46 terminal window using SSH. The command to connect to your virtual machine is:

lab46:~$ ssh root@vm##.student.lab

Managing your virtual machine can be done utilizing the XM tool on the VMServer you created the virtual machine on.

• The command 'xm help' will show you a list of actions you can take.
