Agenda

What’s this all about?

What can you say about any good systems administrator?

They’re lazy...

Why would we say this?

A lot of our daily tasks are repetitive, mundane, and required!!!

So how does that make a good systems administrator lazy?

Using automation, scripting, and doing more with less is lazy!(Insert something about the

economy ‘here’)

Powershell does this!

Powershell loves this!

And it’s easy!

but most of all... ADMINS!

PowerShell?

What is Powershell?

Wikipedia calls it : Windows PowerShell is an extensible command-line shell and associated scripting language from Microsoft. It was released in 2006 ...

We call it : PowerShell is geared around making your life as an ADMIN Easier. PowerShell can be used for:•Scripting! - Automation, Woot!• Interactive Command Shell•GUI!

MSDN calls it : Windows PowerShell is a new Windows command-line shell designed especially for system administrators...

PowerShell & Virtualization

Virtualization Vendor Support for PowerShell:

• Citrix XenServer/XenCenterhttp://community.citrix.com/cdn/xs/sdks

• VMware VI Toolkit for Windowshttp://vmware.com/go/powershell/

• Microsoft SCVMMhttp://www.codeplex.com/PSHyperV

What's Different?

What's Different:• Major feature differences • cmdlet differences• Syntax changes• Maturity

• VMWare!• Hyper-V• Xen

Toolkit Maturity

– VMWare!• Full suite of cmdlets• Well Supported Community• Well published documentation

– Hyper-V• Full suite of cmdlets (SCVMM 2008)• Well published documentation (resources slide)

– Xen• Cmdlets• A few random blog posts• Requires ‘Initialize-XenServer:Aliases’ to behave like

other toolkits.

Putting The Power Into Play

Managing Hypervisors! - Basic Examples

• Storage? Who Needs Storage?

•Networking!

Storage!

• On VMwareo New-Datastoreo Set-Datastoreo Remove-Datastore

• On Xeno Create-Xenserver:SRo Set-Xenserver:SR.*o Destroy-SR

• On Hyper-Vo Handled by Windows/Undocumented...?

Networking! - Virtual Switches

• On VMwareo New/Set/Remove-VirtualSwitcho New/Set/Remove-VirtualPortGroupo New/Set/Remove-VMHostNetworkAdaptor

• On Xeno Create-Xenserver:Networko Set-Xenserver:Network.*o Destroy-Xenserver:Network

• On Hyper-Vo New-VirtualNetworko Get/Set-VirtualNetworko Remove-VirtualNetwork

Demo!

Managing VMs! - Basics

• Pop a VM in the oveno Add VMso Remove VMs

• Whoops! Changes.o Add A NICo Change Memory

• Power Operationso Power Ono Power Off

Pop a VM in the oven.

• On VMwareo New-VMo Get-VM/Set-VMo Remove-VM

• On Xeno Create-XenServer:VMo Get-XenServer:VM/Set-XenServer:VM.* o Destroy-XenServer:VM

• On Hyper-Vo New-VMo Get-VM/Set-VMo Remove-VM

Whoops! Changes.

• On VMwareo Get-VM | Set-VM -MemoryMB 1024o Get-VM | New-NetworkAdaptor

• On Xeno Get-Xenserver:VM | Set-Xenserver:VM.MemoryStaticMax

-Value 1024o Dunno

• On Hyper-Vo Get-VM | Set-VM -MemoryMB 1024o Get-VM | New-VirtualNetworkAdaptor

They happen, heres how you would change memory & network info on a VM

Feel The Power! - Power Operations

• On VMwareo Get-VM -Name $Name | Start-VMo Get-VM -Name $Name | Stop-VM

• On Xen o Get-XenServer:VM | Invoke-XenServer:VM.starto Get-XenServer:VM | Invoke-XenServer:VM.hardshutdown

• On Hyper-V o Get-VM -Name $Name | Start-VMo Get-VM -Name $Name | Shutdown-VM o Get-VM -Name $Name | Stop-VM

Demo!
