Installing and Configuring a VM for whatIf?


Setting up Networking on a new VM

Setup network on VM

  • Open vm software and open the vm file from “My Virtual Machines” and say “I copied it”
  • login as root (pword What1f?)
  • Open the Networking - click on the red hat/system settings/network
  • Probe the machine by:
    • select first (only) profile and click on edit button
    • click on hardware device tab
    • click on probe button
    • click ok button
  • Reset the host name
    • Under DNS tab set Hostname: newName-ux (for example)
    • under File choose Save
  • Take note of the ip address (you'll need it for the next steps in host only mode)
    • Go to the devices tab, double click the eth0
    • Record the static ip address, probably something like:
  • Logout and reboot the machine

VM in NAT mode (only needed if want access to the normal network)

How to get it into nat mode:

  • Make the VMnet8 network connection configuration use DHCP to obtain addres
  • Set the Devices/Network Adaptor on the VM to NAT in the “Settings” of the outer shell of the VM Player
  • In the networking of the VM setup the IP address to come from DHCP
  • Uncheck the “Automatically obtain DNS information from provider
  • Click OK and go to the DNS tab and set:
    • hostname like: red-ux
    • Primary DNS should be: (verify it's the right first part of the domain for the network adapter VMnet8 on host side)
    • Remove the localdomain setting from the DNS search path
  • Save the settings from the Devices tab
  • Shutdown and restart the VM server (I don't think the Reboot option is enough)

Setup network on host

Windows XP

  • On the host machine (windows side) From “Start” menu choose “Connect To/Show all Connections”

Windows Vista & Windows 7

  • On the host machine (windows side) From “Start” menu choose “Network and Internet”

then choose “Network and Sharing Center” and look in the “View your active networks” section of the page

On either system continue with:

  • Choose VMNet1 for host only mode (VMnet8 for NAT mode) connection and look at the properties (right click properties)
    • If you intend to use VMnet1 (which is the default) disable VMnet8
  • Double click “Internet Protocol (TCP/IP)” (on Vista and windows 7 choose TCP/IPv4)
  • Make sure the first 3 parts of the ip address match that of your VM but not the last
    • If VM is in host only mode adjust the host side here (use this option by default)
    • Otherwise, if you want the VM in NAT mode change the VM's ip address inside the VM to match first 3 parts
    • Note: to check your ip address on the VM (if you wish): log in as root, open terminal window and do ifconfig
  • Click OK to save

Check Connectivity

  • Startup the VM you don't need to login
  • Use putty to connect to newName-ux and login as root
  • If you can't get that to work check the host name settings inside the VM networking
  • Add an entry for newName-ux and the corresponding ip address to the host machine's hosts file under (C:\Windows\System32\drivers\etc)
    • To modify hosts file, you will need to run editor program as an administrator and hope the hosts file from inside that program
  • If you still can't get it to work you can use the ip address of the machine which we recorded at the beginning
    • IP address is probably

Setting up Accounts on a new VM

Install Sever Code

  • Get the latest and greatest from the web for samm, whatif, and tool - stick them on the host for now
  • Get the install scripts too!
  • Use winscp to put them in the correct accounts on the machines (note password for tool,samm,whatif same as root by default)
  • Run csh install* for each in the appropriate accounts

Shrinking VM disks

If VMware Tools are installed on your virtual machine (they are on the official whatIf desktop edition), you can use the disk shrink feature to reduce the size of VM files on your host operating system.

  1. Login to the VM's GUI (KDE on Fedora) as root
  2. Open a terminal session
  3. Run the command vmware-toolbox. The VMware Tools Properties dialogue should open.
  4. Select the Shrink tab. Select all the partitions you wish to shrink (multiple selections using ctrl-click. Click the Shrink button.
