  • When editing a machine you can oversubscribe the resources (discovery manager sets CPU to 1 but you can change it to 2).
  • See Workload Level Rule for information on how to modify the oversubscription parameters.

Machines in State MANAGED

  • Compute in Datacenters are not used and the health of a machine is checked before selecting it, only MANAGED machines are considered. The physical machine and Hypervisor are ready to deploy virtual machines.

Enterprise Reservation 

  • The cloud administrator can reserve machines for use by a single enterprise. If a machine is reserved it will only be a candidate if the current virtual datacenter belongs to the same enterprise.

...

Enterprise Exclusion Rule (Affinity) 

  • Enterprises can be explicitly prevented from using physical infrastructure of other enterprises. Defining an enterprise exclusion rule will cause an enterprise to use the same machine for all its virtual machines.
  • exclusion rule is associative (if enterprise 'a' excludes 'b', 'b' also excludes 'a').
  • If the current enterprise is covered by an exclusion rule, all the machines with virtual machines owned by the excluded enterprise will not be candidates.
  • See Restrict Shared Server Rules for more information about configuring these rules.

When deploying a virtual appliance or a single virtual machine the user may see the following errors related to the scheduler logic.

Description

Solutions __________________________


Not enough resources


In the virtual appliance's datacenter, there is no physical machine with enough free resources for the virtual machine's requirements.

  • Add more physical machines.
  • Increase the resources available in a physical machine.
  • Power off some virtual machines.


Resource allocation limits exceeded (Hard limits)


The Resource Allocation Limits configured for the infrastructure do not allow the total resource utilization with the virtual machine requirements.

  • Power off some virtual machines or change the configured limits (0 for unlimited).
  • Increase the hard limits for the enterprise.


Resource allocation limits exceeded (Soft limits)


The Resource Allocation Limits configured for the infrastructure allow the total resource utilization with the virtual machine requirements but alerts users that their resources are reaching the hard limit

  • Power off some virtual machines or change the configured limits (0 for unlimited).
  • Increase the soft limits for the enterprise.
