A virtual machine requires more resources to perform optimally.
Whether this means more RAM, more storage, or more processing power, these resources can be added through a noninvasive process in vCloud Director.
STEP 1: Power off the virtual machine
(NOTE: Generally, it is best practice to create a power the virtual machine OFF before making any changes. However, if you strictly need to add storage space, this can be done without powering the machine off, and you may skip this step.)
Locate the Virtual Datacenter that contains the VM you'd like to modify.
Locate the Virtual Machine you're looking to modify, and select the "Actions" dropdown.
From here, you can Power Off the virtual machine.
STEP 2: Modify Resources
Navigate to the Virtual Machine you'd like to modify, and select "Details"
Select the "Hardware" tab
From this tab, you can make changes to processing power, memory...
NOTE: You will still have to mount any disks you attach to the Virtual Machine. You can do this through Disk Management, just as you might operate a non-virtual machine.
To do this, open the Virtual machine, and log in as an Administrator.
Navigate to Disk Management
Select the volume you'd like to apply the additional storage space to. Right click, and select "Extend Volume"
Follow the Wizard to successfully extend the volume.
Congratulations, you're done!
