Figure 2-4: Single management group containing multiple VM Groups
Creating management groups is nearly identical to creating VM groups using the management tools
previously outlined. The following Windows PowerShell script creates a new management group and
adds both of the existing VM groups to it:
#Create new Management Group
New-VMGroup -Name TestVMGM1 -GroupType ManagementCollectionType
#Setup Management Group variable
$TestVMGM1 = Get-VMGroup -Name TestVMGM1
#Add VM Groups to the Management Group
Add-VMGroupMember -VMGroup $TestVMGM1 -VMGroupMember $TestVMG1
Add-VMGroupMember -VMGroup $TestVMGM1 -VMGroupMember $TestVMG2
An interesting difference between VM groups and management groups is that management groups
can contain both VM groups and other management groups. Put simply, this means that you can nest
management groups.
The following Windows PowerShell script creates a new management group named Outside and adds
our first management group, TestVMGM1, to its membership:
#Create new Management Group
New-VMGroup -Name OutsideGroup -GroupType ManagementCollectionType
#Setup Management Group variable
$OutsideGroup = Get-VMGroup -Name OutsideGroup
#Add VM groups to the Management Group
Add-VMGroupMember -VMGroup $OutsideGroup -VMGroupMember $TestVMGM1
The management group (OutsideGroup) contains another management group (TestVMGM1), which
contains the two VM groups (TestVMG1 and TestVMG2), which contain different groupings of three
VMs (VM1, VM2, and VM3), as demonstrated in Figure 2-5.
