introduction
VApps allow VMs to work together in a stack as an application, and support cloud computing architectures
in previous article we got introduction about vAPP before
this article we will discuss how to configure it in pioneers LAB
network diagram
please have a look to above network diagram
we have vsphere environment which include 6 Virtual machines :
3 windows 10 VMs :
- PC101
- PC103
- PC105
3 Suse Linux VMs :
- SLES131
- SLES132
- SLES133
we will create 2 vAPP :
- vAPP-PCs with normal option and contain windows 10 VMs
- vAPP-Linux with High option and contain Suse Linux VMs
vAPP requirements
In order to use vApps You will need:
- VMware vCenter
- DRS enabled
enable DRS
as we mentioned above :
we have to enable DRS Distributed Resource Scheduler on cluster level
by default DRS is disabled
so we are unable to create vAPP as seen below
to enable DRS :
- open vCenter > cluster > configure > DRS > edit > enable DRS
Create vAPP
after we enable DRS : we can create vAPP
- right click on cluster > new vAPP
move VM to vAPP
after we created vAPP : its time to move each VM to it’s vAPP
we will move SLES131 to vAPP-linux
right click on VM > migrate
repeat same step to move ALL VMs to desired vAPP
set VM power-on /power-off order in vAPP
now vAPP is created and VMs moved inside
we can set order of power-on OR power-off VMs
right click vAPP > edit settings
power-on / power-off VMs in vAPP
to test vAPP functionality : we can click power-on vAPP : which will shutdown ALL VMs inside vAPP based on order
