VM Resources are not Available for Dates Requested

Symptom:

A warning message is displayed to the end user that reads “Unable to fulfill request: Virtual machine resources are not available for the dates requested”. The end user cannot continue to the next step in the reservation wizard.

This message can be displayed for the following reasons:

• The user has already requested the maximum amount of virtual machines that they are allowed to reserve for the time period specified.
• Reservation Manager has determined that none of the ESX servers or clusters that are available to this user have free capacity to accommodate the request for the reservation period.

Solution:

Use one of the following solutions:

1. The user can change the reservation period to a time when resources are available.
2. If the user was prevented from reserving a new virtual machine due to the limit on the number of VMs they are allowed to reserve, increase the limit by modifying the Maximum Systems setting defined for one or more virtual resource pools to which the user has access.
3. If the user was prevented from reserving a new VM because the ESX server capacity limit is too low, modify the associated resource pool. Select Allow memory overcommitment on the Properties tab, and enter a percentage. For more information, see Set Overcommitment of Memory on ESX Server or Cluster.
