  • The "Imported Media File" task fails with the error "Negative uncommittedCapacityMb: -8796093022208"
  • Within the log file /opt/vmware/vcloud-director/logs/vcloud-container-debug you see the following error:

  • This issue can also cause the vCenter Server instance to become disconnected from Cloud Director.


VMware Cloud Director 10.x


This is a known issue caused when vSphere 7.0 Update 2 generates incorrect data regarding storage metrics. This data is then transmitted to Cloud Director and can result in the error "Negative uncommittedCapacityMb" being visible in Cloud Director during certain tasks. For additional information see vSphere KB: KB83990


The issue is resolved in ESXi 7.0 Update 2c (build number 18426014).

Cloud Director 10.3.1 also resolves the issue whereby vCenter Server may disconnect as a result of this problem. Note however that the "Negative uncommittedCapacityMb" error can still be visible until the ESXi patch is applied.


Within vCenter Server, perform a full storage rescan from all ESXi clusters backing the Provider VDC in order to refresh the storage metrics. Allow a few minutes for this data to synchronize in Cloud Director.
