Reviewing My VMs

# Retrieve current inventory of VMs with a particular

properties that are of interest

Get-VM | Select-Object Name, NumCPU, MemoryMB, PowerState,

Host

| Export-CSV Simple_Inventory.csv -NoTypeInformation




Basic Capacity Information

# Total number of hosts

$TotalVMHosts = (Get-VMHost).Count

Write-Host "There are $TotalVMHosts Hosts in

$DefaultVIServer“

# Total number of guests

$TotalVMs = (Get-VM).Count

Write-Host "There are $TotalVMs Virtual Machines in

$DefaultVIServer"




vCheck




Common use cases

Useful one-liners/short scripts

•Deploying Virtual Machines from a Template •Storage vMotion




Deploying Virtual Machines from a Template

$vms = Import-CSV C:\NewVMs.csv

foreach ($vm in $vms){

$Template = Get-Template $vm.Template

$VMHost = Get-VMHost $vm.Host

$Datastore = Get-Datastore $vm.Datastore

$OSCustomization = Get-OSCustomizationSpec $vm.Customization

New-VM -Name $vm.Name -Template $Template -VMHost

$VMHost -Datastore $Datastore -OSCustomizationSpec

$OSCustomization -RunAsync

}




Storage vMotion

$vms = Import-CSV C:\StorageVMotion.csv

foreach ($vm in $vms){

Get-VM $vm.Name | Move-VM -Datastore $vm.TargetDatastore

How do we deploy our image ?




New host deployment method introduced in vSphere 5.0

• Based on PXE Boot

• Works with Image Builder, vCenter Server, and Host Profiles

• How it works:

• PXE boot the server

• ESXi image profile loaded into host memory via Auto Deploy Server

• Configuration applied using Answer File / Host Profile

• Host placed/connected in vCenter

• Benefits

• No boot disk

• Quickly and easily deploy large numbers of ESXi hosts

• Share a standard ESXi image across many hosts

• Host image decoupled from the physical server

• Recover host w/out recovering hardware or having to restore from backup

• Update of Image is just a reboot

What Is Auto Deploy




No Boot Disk? Where does it go?

Boot Disk

Image Profile

Host Profile

vCenter Server

Add-on Components

Platform Composition: ESXi base,

drivers, CIM providers, …

Configuration: networking, storage,

date/time, firewall, admin password, …

Running State: VM Inventory,

HA state, License, DPM configuration

Event Recording: log files, core dump
