Step 30: After first reboot, you’ll see this screan.
Step 31: Select “Firewall configuration” and disable it.
Step 32: Select “Services configuration”:
Step 33: Leave enable only these services for minimal installation:
Step 34: Reboot your virtual machine.
Step 35: Login your VM and execute:
Step 36: Remove HWADDR line to prevent ethernet issues.
Step 37: Copy ethernet configuration.
Step 38: Execute Set-LinuxVM to give internet access to VM. So we can do latest updates.
Step 39: Execute the command below to update your VM.
Step 40: Clear ethernet configuration.
Step 41: Clean bash history with the command below.
Step 42: Turn off your Virtual Machine.
Step 43: Right click on Virtual Machine and click “New template”.
Step 44: Put template information.
Step 45: Leave hardware properties as default.
Step 46: Most important! Choose “[Customization not required]” to provision Linux VMs.
Step 47: Choose your library server, then choose a share path.
Step 48: Click “Create” button to start creation process.
Step 49: Go to template properties. Type distro name to the “Tag” field.
Step 50: Go to “Custom Properties” tab. Type username into first field, type password into second field.
So with these changes, Set-LinuxVM looks for distro, username and password information from template.
If you create a Linux VM from this template, use Set-LinuxVM like below:
You should use Set-LinuxVM version 2.3 or newer to use template functionality.

Step 9: Press Enter to start CentOS 5.6 x64 installation.
Step 10: Skip CD checking and choose a language.
Step 11: Choose keyboard and click “Next”.
Step 12: You will see a warning about initializing disk drive. Click “Yes” and continue:
Step 13: Click “Review and modify partitioning layout” and click “Next”.
Step 14: Click “Yes” for warning to continue:
Step 15: Delete pre-defined volumes by clicking “Delete” button.
Step 16: After you clear volumes, go to LVM and click “Edit” button.
Step 17: Click “Add” button to create new partitions in LVM.
Step 18: Create mount points and sizes as you want.
Step 19: As an example, I create a Swap partition as 8192 MB. Because swap should be twice of your memory.
Step 20: Create /tmp mount point as 4096 MB.
Step 21: Use all available space for / mount point. In this case I have only 8064 MB disk space.
Step 22: So final partitioning layout should be:
Update: You should first create / mount point. Otherwise you can’t extend LVM with Set-LinuxVM.
Step 23: Next page, choose “GRUB boot loader” and click “Next”.
Step 24: Leave all default but clear “Active on Boot” option.
Step 25: Choose your timezone and next page assign a root password.
Step 26: Clear the click of “Desktop Gnome” and click “Customize Now”.
Step 27: Click “Development Libraries” and “Development Tools”, then click “Next”.
Step 28: You can start installation by clicking “Next”.
Step 29: After installation complete, reboot virtual machine.

Now it’s possible to use Linux VM templates on SCVMM 2008 R2 for quick deploys if you use “Set-LinuxVM”. We just need a clean Linux template for quick deploys.
Lets start with creating our Linux VM. Go to SCVMM and click “New Virtual Machine”.
Step 1: Choose “Create the new virtual machine with a blank virtual hard disk” and click “Next”.
Step 2: Give a name and description for your Virtual Machine and click “Next”.
Step 3: You should be careful about CPU, memory and network adapter. As an example, hardware profile should be:
Memory: 4096 MB
Disk: 20 GB
It’s very important to use 1 vCPU and emulated network adapter with your Linux VM template. I assign 4096 MB memory to virtual machine because usually I setup virtual machines with that memory value. If you usually setup VMs with 2048 MB memory, then give that! I assign 20 GB of disk space because I’ll split that into partitions for best performance. I’ll also use Logical Volume (LVM) to extend volumes with “Set-LinuxVM“.
Step 4: Next screen, choose “Place the virtual machine on a host”.
Step 5: Select a host and storage volume, then click “Next”.
Step 6: Choose Virtual Network for VM and click “Next”.
Step 7: Set additional properties and click “Next”.
Step 8: Click “Create” and finish this proccess.
After a minute, your VM will be up and ready for CentOS installation.
