VMware vCloud Director does not report CPU consumption on Allocation Pool based Organization Virtual Data Centers

Products

• VMware

Issue/Introduction

Symptoms:

• When viewing the list of Organization Virtual Data Centers (VDCs) in VMware vCloud Director (vCD), the Processor column of an Allocation Pool based VDC does not report the CPU consumption.
• In the mouse over tool tip, you see that the Allocation consumption is 0% and Reservation consumption is 0%.

Resolution

This issue is resolved in vCloud Director 5.5.2, available at VMware Downloads. For more information, see the vCloud Director 5.5.2 Release Notes.

If you do not want to upgrade, use the work around:

To work around this issue, upgrade to vCloud Director 5.1.2 and enable the Elastic Allocation Pool mode.

To enable the Elastic Allocation Pool mode:

1. Log in to the vCloud Director Web user interface as a System Administrator.
2. Click Administration.
3. Click General under System Settings.
4. Select the Make Allocation pool Org VDCs elastic option located at the bottom of the page, under Miscellaneous.
5. Click Apply.

Note: It may take a few minutes for the vCloud Director database to refresh its cache to update the CPU consumption values and apply the setting.

VMware vCloud Director が、組織VDC上のアロケーションプールにおいてCPU消費をレポートしない

Impact/Risks:
There are two functional modes for Organization Virtual Datacenters (Org vDC) based on the Allocation Pool Model:

1. Single Cluster Allocation Pool (SCAP)
2. Elastic Allocation Pool

In earlier versions of vCloud Director 5.1.0, all Allocation Pools were functional only in SCAP mode since the feature did not exist. In vCloud Director 5.1.0, Allocation Pools only function in Elastic mode. In vCloud Director 5.1.2, there is an option to change between modes in a global fashion. You cannot have a subset Organization vDCs act in SCAP mode and the compliment act in Elastic mode.

When vCloud Director is running in SCAP mode:

• Allocation Pools are limited to deploy the Primary Resource pool of the Provider vDC.
• The properties of the Org vDC does not show a vCPU Frequency option.
• Consumption of the CPU Reservation in the Allocation Pool is 0, which is normal and expected.

When vCloud Director is running in Elastic Allocation Pool mode:

• Virtual machines can be deployed in any Resource Pool of the Provider VDC
• The properties of the Org vDC have a vCPU Frequency option. This works similar to the Pay-As-You-Go Org vDC model.
• Consumption of the CPU Reservation in the Elastic Allocation pool is a sum of the powered on virtual machines which have a guarantee configured on them.
  

Note: When switching between modes, guarantees are only applied to virtual machines at the time virtual machine is powered on. It may be required to stop and start the vApps inside the Org vDC to update their values as per the new Org VDC settings.

For more information about the differences between enabling and disabling Make Allocation pool Org VDCs elastic, see the Understanding Allocation Models section in the vCloud Administrator's guide.
