Deploying vCenter Operations Management Suite start vAPP error

My company decided that we should give vCenter Operations Management Suite a go as we needed a tool which gives us the capacity planning. It used to be capacity IQ but now it is bundled as part of this suite. https://www.vmware.com/products/datacenter-virtualization/vcenter-operations-management/features.html

The product comes as a vAPP ( 2 VMs) which makes life easier to deploy but as I try to power on the vAPP I get this error "Cannot initialize property 'vami.netmask0.VM_1', since network 'PPE-Servers-1' has no associated IP pool configuration.". If this comes up for you then you will need to redeploy the vAPP following the steps below

The error does give a hint that you need "IP pool" so my first point of call was to go to vCenter and look under "networking" but there are no tabs or options to create IP Pool. In the end I found it under "Home > Inventory > Datastores and Datastore Clusters"

Highlight your datacenter and you will see the tab "IP Pools" Click on "Add"



Give the IP Pool a name, If you are using IPv4 fill in the details of the subnet and gateway address for it. Tick box "Enable IP Pool", no need add address range unless you wish the appliance to get an address from here.

 

Select "DNS" tab and fill in any information about your sites DNS settings

Select "Associations" tab and tick box which network the IP pool belongs to.

Now you are all ready to deploy the vAPP again and this time it should just work.
