Intermittent provisioning issues and generic errors when Composer and vCenter Server are co-installed (2105261)

  • 4 Ratings


  • Composer is co-installed with the vCenter Server
  • You experience intermittent provisioning issues that are not isolated to a pool or parent image
  • You may see these errors:

    • Error during provisioning: A general system error occurred
    • View Composer Fault: Unexpected VC fault from View Composer
    • Provisioning error occurred for Machine ... Unable to remove Machine from inventory
    • Error during provisioning: A general system error occurred

  • In the composer.log file, you see entries similar to:

    • FATAL | CommonLib.VcSubsystem.VcUtil - ManagedObjectNotFoundFault fault was thrown by the VC server.System.Web.Services.Protocols.SoapException: The object has already been deleted or has not been completely created
    • FATAL | CommonLib.VcSubsystem.VcUtil - VC connection exception.
    • FATAL | CommonLib.VcSubsystem.VcSubsystem25 - Failed to disconnect to the VC server at: https://vcenterHostaname:443/sdk


This issue occurs because insufficient system resources are allocated to the operating system of the virtual machine, hosting the Composer and vCenter Server services.

A simple installation of the vCenter Server can require at minimum between 8GB and 12GB of RAM. A standalone installation of Composer recommends 8GB of RAM. Co-installing the composer service without increasing resources of the vCenter Server can cause undue resource contention.


To resolve this issue, ensure that enough resources are assigned to the virtual machine hosting vCenter Server and View Composer.
To ensure if enough resources are assigned to the virtual machine hosting vCenter Server and View Composer:
  1. Disable provisioning in the View administrator for the affected vCenter Server.
  2. Shutdown the vCenter/Composer Server and increase the vCPU's and RAM resources to account for the services installed.
  3. Power on the vCenter/Composer Server.
  4. Re-enable provisioning in the View administrator.
