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!

Who Are We?

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/XenCenter http://community.citrix.com/cdn/xs/sdks
VMware VI Toolkit for Windows http://vmware.com/go/powershell/
Microsoft SCVMM http://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

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 VMware
New-Datastore
Set-Datastore
Remove-Datastore
On Xen
Create-Xenserver:SR
Set-Xenserver:SR.*
Destroy-SR
On Hyper-V
Handled by Windows/Undocumented...?

Networking! - Virtual Switches
On VMware
New/Set/Remove-VirtualSwitch
New/Set/Remove-VirtualPortGroup
New/Set/Remove-VMHostNetworkAdaptor
On Xen
Create-Xenserver:Network
Set-Xenserver:Network.*
Destroy-Xenserver:Network
On Hyper-V
New-VirtualNetwork
Get/Set-VirtualNetwork
Remove-VirtualNetwork

Managing VMs! - Basics
Pop a VM in the oven
Add VMs
Remove VMs
Whoops! Changes.
Add A NIC
Change Memory
Power Operations
Power On
Power Off

Pop a VM in the oven.
On VMware
New-VM
Get-VM/Set-VM
Remove-VM
On Xen
Create-XenServer:VM
Get-XenServer:VM/Set-XenServer:VM.*
Destroy-XenServer:VM
On Hyper-V
New-VM
Get-VM/Set-VM
Remove-VM

Whoops! Changes.
On VMware
Get-VM | Set-VM -MemoryMB 1024
Get-VM | New-NetworkAdaptor
On Xen
Get-Xenserver:VM | Set-Xenserver:VM.MemoryStaticMax -Value 1024
Dunno
On Hyper-V
Get-VM | Set-VM -MemoryMB 1024
Get-VM | New-VirtualNetworkAdaptor
They happen, heres how you would change memory & network info on a VM
