Group vm.13327: Cannot admit VM: Memory admission check failed. Requested reservation: 311199 pages

Solution

This issue ocuurs when:

User or Distributed Resource Scheduling (DRS) have assigned limited resource to a resource pool.

Virtual machine's host does not have enough memory for the reservation required.

Virtual machine's resource usage does not match its resource settings.

Note: You must have available memory for any memory reservations you have set for the virtual machine and the overhead memory. For more information on determining overhead memory requirements, see vSphere Resource Management section in the ESXi and vCenter Server 5.5 Documentation Guide.

To resolve this issue:

Increase the resource allocation for the resource pool. For more information, see Powering on a virtual machine from within vCenter times out (1006017).

Reduce permitted reservations for an virtual machine. For more information, see the vSphere Resource Management section in the ESXi and vCenter Server 5.5 Documentation Guide.

If applicable, remove VMDirectPath devices from the virtual machine. Adding a VMDirectPath device to a virtual machine sets memory reservation to the memory size of the virtual machine. For more information, see the Configuring Resource Allocation Settings settings in the ESXi and vCenter Server 5.5 Documentation Guide.

Increase physical host resources, such as memory.
