VMware vCenter Server 5.1 Update 1b Release

The 1:st of August VMware released the vCenter Server 5.1 U1b. This release does not bring any new features or functions, it focuses on bug fixes.
I just wanted to point out one specific bug fix that will justify an upgrade to the newest vCenter Server version for at least one of my customers.

  • vCenter Server stops responding frequently with the Win32 exception: Access Violation (0xc0000005) message in the log file.
    Two concurrent calls to retrieve information from the same host might cause the vCenter Server to stop responding frequently. The vpxd log files might display messages similar to the following:
    [16064 verbose 'VpxProfiler' opID=e05b1f14] [1-] [VpxdVdb] LoadCLOB: vim.host.SystemResourceInfo (took 1014 ms)
    [16064 panic 'Default' opID=e05b1f14] (Log recursion level 2) Win32 exception: Access Violation (0xc0000005)
    Read (0) at address ffffffffffffffff

    r14: 0000000177eff330 r15: 000000002c95a228

The fix for the below described bug can alone justify an upgrade to the newest vCenter Server version.

  • All virtual machine folders on a VMFS volume are deleted after a single virtual machine folder is attempted for delete resulting in failure, and you choose Delete again by using the Datastore Browser.
    When you attempt to delete a virtual machine folder while the virtual machine is powered on, a message similar to Cannot delete file. [VMFS] <virtual_Machine_Name> is displayed. If you click the Delete button again without closing the datastore browser or changing the selection, and attempt to delete the same virtual machine folder that failed to delete earlier, all virtual machine folders on the VMFS volume might now get deleted.

There is no new release for the hypervisor, ESXi, at this time. VMware ESXi 5.1, Patch Release ESXi510-201307001 was released the 25:th of July and can be downloaded here.
