خوب خود سایت وی ام ور هم نوشته این مشکل به سه دلیل است و سه راه حل داده :
مشکلی که گفتید به سه دلیل :

This issue occurs when:

• A user or Distributed Resource Scheduling (DRS) has assigned too few resource to a resource pool.
  
• A virtual machine's host does not have enough memory for the reservation required.
  
• A virtual machine's resource usage does not match its resource settings.
  

Note: You must have enough available memory for any memory reservations you have set for the virtual machine and the overhead memory. For more information on determining your overhead memory requirements, see the vSphere Resource Management guide.

حالا راه حلی که ارائه داده به شرح زیر است :

o resolve this issue:

1. Increase the resource allocation for the resource pool. For more information, see Powering on a virtual machine from within vCenter times out (1006017).
2. Reduce permitted reservations for a virtual machine. For more information, see the vSphere Resource Management Guide for your version of vSphere.
3. 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 Configuration Guide.
4. Increase physical host resources, such as memory.
