What’s New

This release of VMware vCenter Server 5.1.0a includes a number of bug fixes that have been documented in theResolved Issues section.

Upgrades for This Release

For instructions about upgrading vCenter Server and ESX/ESXi hosts, see the vSphere Upgrade documentation.

  • Upgrade and Installation

    • vCenter Server Services fail on startup after upgrade to vCenter Server 5.1
      After you upgrade to vCenter Server 5.1, the vCenter Server services fail to start up and generate vpxd dumps. This issue occurs if old certificates are removed during upgrade of vCenter Server or if you attempt to perform a fresh install of vCenter Server with an already upgraded vCenter Server 5.1 database.

      This issue is resolved in this release. If you have encountered this issue in the past, upgrading to vCenter Server 5.1.0a will resolve the issue.

    • Users unable to log in to vCenter Server after upgrading to vCenter Server 5.1
      After upgrading to vCenter Server 5.1, you might be unable to log in with the user or group administrator privileges provided by the vCenter Server installer during the upgrade process. This issue can occur if vCenter Server finds a vCenter Server Administrator user or group that can be authenticated against vCenter Single Sign On while searching the vCenter Server database.

      This issue is resolved in this release.

    • Invalid solution certificate. Certificate already expired. error message occurs when upgrading to vCenter Server 5.1 and registering the vCenter Server instance to vCenter Single Sign On 
      The vCenter Server installer does not allow upgrade if the certificate is invalid or already expired. To regenerate expired SSL certificates, see KB 1009092: Regenerating expired SSL certificates.

      This issue is resolved in this release.

    • vCenter Server takes an unusually long time to start and the vSphere Client might time out
      When a large number of permissions are assigned to objects in the vCenter Server inventory, the vCenter Server service does not start as quickly as expected as vCenter Server verifies that the users and groups exist in the identity source. Also, the connection to the vSphere Client might time out when you log in with Windows session credentials.

      The following messages appear in the vCenter Server logs while the service is starting:

      [SSO] [SsoAdminFacadeImpl] [FindGroup]
      [UserDirectorySso] GetUserInfo (DOMAIN\ *USER OR GROUP*, true) res: DOMAIN\ *USER OR GROUP*
      [UserDirectorySso] NormalizeUserName (DOMAIN\ *USER OR GROUP*, false) re: DOMAIN\ *USER OR GROUP*

      This issue is resolved in this release.

    • Upgrading to vCenter Server 5.1 might fail with error 29107 even though the service or solution user is already registered
      Attempts to upgrade vCenter Server 5.1 might fail with the following error message:

      Error 29107. The service or solution user is already registered. Check VM_ssoreg.log in system, temporary folder for details.

      This issue is resolved in this release.

    • Installing or upgrading vCenter Server 5.1 fails with the error: Could not contact Lookup Service
      vCenter Simple Install might fail with the following error if the Fully Qualified Domain Name (FQDN) contains the string port during the installation:

      Error 29102 . Could not contact Lookup Service. Please check VM_ssoreg.log in system temporary folder for details.

      This issue is resolved in this release.

    • Installing vCenter Single Sign On fails with the error: Unable to create database users: Password validation failed
      When you attempt to install vCenter Single Sign On using an existing database or the bundled SQL Express database, the installation fails with the following error:

      Error 29114. Cannot connect to DB

      This issue is resolved in this release.

    vCenter Server and vSphere Client

    • Unable to log in to the vSphere Web Client due to incorrect proxy settings
      Slow network speeds caused by incorrect proxy settings might result in delay during the interaction between the vSphere Web Client, domain controller, and external vCenter Single Sign On. You might encounter the following issues due to this delay:

      • Attempts to log into the vSphere Web Client fail with the following error:The vSphere Web Client cannot connect to the vCenter Single Sign On server.
      • A delay in excess of 20 minutes to list all domain users
      • A delay in excess of 20 minutes to load the whole vCenter Server inventory after domain use login

      This issue is resolved with this release.

    vMotion and Storage vMotion

    • Unable to access the cross-host Storage vMotion feature from the vSphere Web Client with an Essentials Plus license
      If you start the migration wizard for a powered on virtual machine with an Essentials Plus license, the Change both host and datastore option in the migration wizard is disabled, and the following error message is displayed:

      Storage vMotion is not licensed on this host.
      To perform this migration without a license, power off the virtual machine.

      This issue is resolved in this release.

    Hmm i’ve updated to this version, and to the newest version of vCenter Converter, but P2V dosen’t seem to be working yet :(

    1. Mladen Bonev

      I assume you used Converter 5.0.1, correct? When you say P2V doesn’t work do you mean Converter stops responding when you target it to vSphere 5.1.0a or the actual P2V conversion fails?

  2. iwan rahabok

    Thanks. What’s the reason for calling it 5.1.0a instead of 5.1.1 (like the rest of vCloud Suite)?
    In general, when do we use “a, b, c, etc” instead of “x.x.1, x.x.2, etc”?
    Thanks from Singapore! e1

    1. Justin King

      the reason this is released as 5.1.0A is because it is a minor release to patch some software glitches customers experienced with install/upgrades of the recent release of 5.1.0 GA

    1. John

      Hmmm. Rolling out into production before clear testing is not a nice thing to do to your clients : )

      1. Brett

        I would agree however why has it become the responsibility of the consumer to test a product. When VMware say GA that should mean good enough for production right now! This is how we do software releases here just goes to show who is willing to stand by their word.

        Now if VMware released an RC version for testing then I can understand.

  3. Vitor Euphrasio

    When I try to Update the vCenter 5.1 to 5.1.0A i got and error (just the vCenter Server, the SSO, Inventory and Web worked fine).

    “Error 1335: The cabinet file ‘VPX.cab’ required for this installation is corrupt and cannot be used. This could indicate a network error, an error reading from the CD_ROM, or a problem with this package.”

    I downloaded 3 times the *.ISO, check the CheckSum and it´s ok. Any ideia?

    1. Lukas Radil

      Hi,
      I’ve experienced with same problem. I’ve disabled UAC and then installation works fine.

    Judging by all of the research that has been done, it seems that
    some antioxidants are important to some parts of the body, but not to others.

    Bring to a boil, then cover, reduce heat to medium-low
    Simmer until the lamb is tender, about 15 minutes.
    You can add vanilla protein powder such as rice protein and make a thick shake and
    then freeze it in custard cups.

    We have just designed a computer program that will readily

    Think you’re questioning to look at it?

    First of all I would like to say excellent blog! I had a
    quick question that I’d like to ask if you do not mind.
    I was interested to know how you center yourself and clear
    your thoughts before writing. I’ve had a difficult time clearing my thoughts in getting my thoughts out.
    I truly do enjoy writing but it just seems like the first 10 to 15
    minutes are generally wasted simply just trying to figure out how
    to begin. Any ideas or tips? Many thanks!

    Wow! This blog looks exactly like my old one!

    It’s on a entirely different topic but it has pretty much the same page layout and design.

    Outstanding choice of colors!

    Their web Host – uswekaju.tumblr.Com
    - had emailed Formstack, LLC three weeks prior to the maintenance to warn about the impending downtime, but didn’t remind the company closer to
    the day that the downtime was scheduled. You have no way of knowing what your
    needs will be a year from now. Web sites need to be operational 24
    hours a day, 7 days a week, and 365 days a year.

    Yesterday, while I was at work, my sister stole my apple
    ipad and tested to see if it can survive a thirty foot drop, just
    so she can be a youtube sensation. My iPad is now broken and she has
    83 views. I know this is totally off topic but I had to share it with someone!
