Adjust Virtual Machine Resources
You can adjust the resources—CPU, memory, and storage—of a virtual machine in
Virtual Private Cloud OnDemand.
You can hot-add resources (CPUs, memory, and storage) to a powered on virtual machine in
Virtual Private Cloud OnDemand without having to re-provision the virtual machine. However, the
following caveats apply:
n
Depending on the guest OS of the virtual machine, you might need to reboot the instance for the change
to be recognized.
n
Some guest operating systems (such as Ubuntu templates) do not support hot-adding resources. When
a guest OS does not support resource hot-add, the Edit Resources option is disabled for the powered on
virtual machine. For these operating systems, power off the virtual machine before adjusting resources.
For information about the capacity maximums for virtual machines in Virtual Private Cloud OnDemand,
see “Capacity for Virtual Private Cloud OnDemand,” on page 48.
Prerequisites
You have the required permission to manage the virtual machine. If you are a member of the End User role,
you are the virtual machine owner or you are a Virtual Infrastructure Administrator. The owner of the
virtual machine is the user who created the virtual machine or who was transferred ownership of the virtual
machine.
Procedure
1 Select the virtual machine for which you want to adjust resources.
2 From the Actions menu, select Edit Resources.
The Edit Resources dialog appears.
3 Adjust the resources for the virtual machine. (By default, the service allocates resources to the virtual
machine based on the template selected.)
n
CPU: The number of vCPUs for the virtual machine
n
Memory: The total amount of vRAM for the virtual machine
NOTE CPU and memory resources are linked. Click the link icon ( ) to adjust the number of
vCPUs and amount of memory individually.
When the CPU and memory settings are linked, the resource allocation predefines a ratio of vCPUs
to a minimum and maximum memory range. The predefined ratio provides the best performance
for the virtual machine in the Virtual Private Cloud OnDemand environment.
n
Storage: For the disk you want to modify, enter a new allocation value and select the storage tier
from the drop-down menu.
See “Overview of Storage Tiers,” on page 29 for information.
4 Click Save.
