Selecting the Appropriate VMware Infrastructure Management Installer
For the Virtual Center Server 2.5 Update 6c release only zip files for the two builds of VMware Infrastructure Management Installer are available for download. Select one of the following options:
- VMware-vpx-2.5.0-943004.zip - These files include an English-only version of the VI Client, which runs in English regardless of the language of the Windows system. Use this installer to install a VI Client that will run in English on Chinese, German, or Japanese versions of the Windows operating system.
- VMware-vpx-2.5.0-988558.zip - These files include a localized installer that installs all files needed to run in English, Chinese, German, or Japanese. The VI Client used at runtime corresponds to the locale of the current Windows operating system if the locale is Chinese, German, or Japanese. On Windows operating systems set to locales other than Chinese, German, or Japanese, the English version of the VI Client is used.
Changes to Virtual Infrastructure Client Installer
The VI Client standalone installer (available from ESX Server Web Access) allows installation of the VMware Infrastructure Update service, which is used for updating and patching ESX Server 3i hosts. The standalone VI Client Installer is now modified to allow optional installation of the VMware Infrastructure Update service. The VirtualCenter Unified Installer (available as part of the VirtualCenter 2.5 Update 6 download) now includes an option to install VMware Infrastructure Update service when you choose the VI Client installation option.
Upgrading or Migrating to VirtualCenter 2.5 Update 6c
This release supports upgrading from VirtualCenter 2.5 Update 6 and VirtualCenter 2.5 Update 6b to VirtualCenter 2.5 Update 6c. Review the detailed upgrade and migration instructions and guidelines that are provided in the Upgrade Guide.
Refer to the Solution Upgrade Path section of the VMware Product Interoperability Matrix for more information on the supported upgrade paths.
Upgrading VMware Infrastructure Client
During upgrade of VirtualCenter Server to VMware Infrastructure 2.5 Update 6c, you can choose to upgrade both VMware Infrastructure Client and VirtualCenter Server to 2.5 Update 6c version. You must use only the upgraded VI Client to access VirtualCenter 2.5 Update 6c. The VI Client upgrade is mandatory. You can upgrade VI Client by clicking the VIClientinstaller.exe file.
Note: While attempting to upgrade the old VI client, you might be prompted that another version of VI client is already installed on the system. In such a scenario, you must uninstall the old VI client and install the latest version.
Plug-In Updates
This release of the VMware Infrastructure 3 software suite does not include an update to VMware Update Manager.
Resolved Issues
- Oracle (Sun) JRE is updated to version 1.5.0_38, which addresses multiple security issues that existed in earlier releases of Oracle (Sun) JRE. Oracle has documented the CVE identifiers that are addressed in JRE 1.5.0_38 in the Oracle Java SE Critical Patch Update Advisory of October 2012.
- VirtualCenter Server and VI Client contain a vulnerability in the handling of the management authentication protocol. To exploit this vulnerability, an attacker must convince either VirtualCenter Server or VI Client to interact with a malicious server as a client. Exploitation of the issue might lead to code execution on the client system.
To reduce the likelihood of exploitation, Virtual Infrastructure components should be deployed on an isolated management network.
The Common Vulnerabilities and Exposures Project (cve.mitre.org) has assigned the name CVE-2013-1405 to this issue.This issue is resolved in this release.

Applications Running on the Virtual Machine Might Throw Errors During Quiesced Snapshot Creation
Taking quiesced snapshots of a virtual machine requires interaction with the applications running on it. If an application is experiencing high levels of load, it might cause issues during quiesced snapshot creation. These issues might be either application errors, such as failure to write data to disk, or errors in taking the snapshot.
You can clone a powered-on virtual machine. This, however, involves a quiesced snapshot creation, and you might get errors, if a high-load application is running on the virtual machine.
Note: You can run custom scripts in the virtual machine as part of the quiesced snapshot creation operation. These scripts might be used to shut down the application and bring it back up after the snapshot creation. To know more about running such custom scripts, refer to the "VMware Consolidated Backup" chapter of the "Virtual Machine Backup Guide" in the VMware Infrastructure Documentation Set.
CIM and API
-
VI Client Displays Incorrect Name for Power Supply Redundancy Sensor on HP Servers
When you use the VI Client to connect to an ESX Server installation on an HP server system, the VI Client incorrectly displays the power supply redundancy sensor on the server as a physical power supply source. For example, for an HP server with redundancy sensor that has two physical power supplies, the VI Client displays the redundancy sensor as Power Supplies for Power Supply 3. -
Some CIM Classes Do Not Work Properly on IBM Multinode Systems
For the following classes, the EnumerateInstance()operation returns one instance less than the EnumerateInstanceNames() operation:
- CIM_AssociatedSensor
- CIM_MemberOfCollection
For the following classes, the GetInstance operation fails for some instances. However, the EnumerateInstances() operation succeeds.
- CIM_HostedService
- CIM_Sensor
- CIM_SystemDevice
- CIM_Slot
- CIM_ElementConformsToProfile
For the following classes, the EnumerateInstances() and EnumerateInstanceNames() operations fail to return any results:
- CIM_OwningCollectionElement
- CIM_RedundancySet
-
Operation RequestStateChange(RestoreDefaultThresholds) Results in Error
In the ESX Server 3.5 release, the operation RequestStateChange(RestoreDefaultThresholds) results in the following error message for some sensors:
CIM_ERR_FAILED: index out of bounds
In spite of the error message, the CIMOM does restore the thresholds. - InvokeMethod(RequestStateChange) for either Sensor and SEL fails when you use the WS-Man protocol.
-
Firewall on ESX Server 3.5 Interferes with CIM Indication Support
Outgoing HTTP connections are blocked by the firewall on ESX Server 3.5. This prevents indications from reaching the indication consumer.
Workaround: In the service console, open an outgoing port for connections to the indication consumer by using the following command:
esxcfg-firewall -o <port-number>,tcp,out,http
To close a port for HTTP in the firewall:
esxcfg-firewall -c <port-number>,tcp,out,http - On HP 380 G5 machines running ESX Server 3.5 Update 2 or higher, the IPMI board's IP address is not returned in response to CIM_IPProtocolEndpoint queries.
- openwsman indications do not work on ESX Server 3.5 Update 2 or higher when you use the WS-Man protocol.
- On IBM IBM x3850 M2 and x3950 M2 servers, some OMC_DiscreteSensor instances are found to have incorrect device IDs (with -1 as the last segment of the device ID).
- The ModifyInstance() call to change sensor threshold fails when you use the WS-Man protocol.
- Chassis intrusion indication is not available for IBM Athena servers.
- On some Dell MLK hardware, the NumberOfBlocks property for the OMC_Memory instance has a value of 0.
Guest Operating Systems
- VMware Update Manger 1.0 bundled with vCenter Server 2.5 Update 6.x might fail to download patches for Windows virtual machines*
-
Windows Guest Operating Systems Might Fail to Resume from Standby or Hibernation State
Virtual machines running Windows Server 2008 and Windows Server 2003 based guest operating system in the standby or hibernation state might fail to resume from standby or hibernation states.
See KB 946331 on the Microsoft support Web site. -
x64-based versions of Windows Vista and Windows Server 2008 guest operating systems require Microsoft hotfix
x64-based versions of Windows Vista and Windows Server 2008 guest operating systems without Microsoft hotfix http://support.microsoft.com/kb/950772 might encounter an issue where the guest operating system stops responding and returns the following error:
MONITOR PANIC: vcpu-3:ASSERT vmcore/vmm/cpu/segment.c:430 - VMware Tools Upgrade on Linux Guests Requires Manual Network Service Restart (KB 1004322)

Internationalization
All fields in the VI Client and the VI Web Access support non-ASCII character input, except for the following limitations:
Non-ASCII Character Entry Limitations
- Specifying a non-ASCII value as an input string is not supported on the remote command line interface (RCLI).
- The name of the computer on which VMware Infrastructure 3 or any of its components are installed must contain only ASCII characters.
- If the name of the computer or virtual machine where VirtualCenter Server is being installed uses a non-ASCII computer name, the installation of VirtualCenter Server fails.
- Use the default installation path names specified in the installer for all the components. Do not change the install path, because the installer does not support installation path names containing non-ASCII characters and extended-ASCII characters.
- Datastore names, virtual network names, and image file names (CD, DVD, and floppy drive) are restricted to ASCII characters only.
- Message of the Day must use only ASCII characters.
- Logging in to the VirtualCenter Server is supported for user names with ASCII characters only (login account name on Windows).
- Image customization might fail if non-ASCII characters are used.
- Custom attribute names and values must use only ASCII characters.
- To conform to the general Internet practice and protocols, the following cannot contain non-ASCII characters: host names, workgroup names, domain names, URLs, email addresses, SMTP server names, and SNMP community string.
- Guest operating system customizations using ASCII encoding are supported, but customizations using UTF-8 encoded native characters of Japanese, Chinese, or German have limited support. For customizations with non-ASCII owner, organization, user name, or password, VirtualCenter and the sysprep tool must be hosted in the same locale as that of the guest OS. This includes the scenario to use UTF-8 encoded answer file.
Non-ASCII Character Display Limitations
- When managing a VirtualCenter Server with a VI Client running on different languages of Windows, you might see some characters displayed incorrectly because of the difference in language-specific support on Windows.
- If an error message includes log locations or user names containing non-ASCII characters, it will not appear correctly in a localized environment.
- When you use the Import Wizard of VMware Converter, the date and time format is sometimes inconsistent with the current locale.
- Unicode characters are displayed as '???' under the Status column and the Task Details of the Task View tab in the Japanese locale.
- The Commands section on the Summary tab is not displayed properly.
-
Non-ASCII Character Cannot Be Used in the Datacenter Names of a Localized VirtualCenter 2.5 Update 5 if VirtualCenter Is Upgraded from VirtualCenter 2.0.2
After you upgrade from VirtualCenter 2.0.2 to a localized version of VirtualCenter 2.5 Update 5, if you use non-ASCII characters in the datacenter names of VirtualCenter 2.5 Update 5, and then restart the VMware VirtualCenter Server service, every character in the datacenter names is replaced with the ? character.
Workaround: VirtualCenter 2.0.2 supports only ASCII characters in the datacenter names. Even after the upgrade, use ASCII characters in the datacenter names.
Guided Consolidation Limitations
The Guided Consolidation tab is available only in the en_US locale.
Translation Issues

LSI jobs and nonconcrete storage pools do not persist between boots
The persistence scheme implemented by LSI creates a new file on the host operating system for each job and non-concrete storage pool (a storage pool that is not associated with a storage volume). These files do not persist between boots. As a result, non concrete storage pools are not available after the host operating system is rebooted. In addition, any jobs that are run before the reboot are not visible. - Support for 10GbE IP storage (iSCSI and NFS) with the Update releases of ESX Server 3.5, ESX Server 3i version 3.5 Installable, and ESX Server 3i version 3.5 Embedded is for connectivity. Performance levels might vary.

Upgrading VirtualCenter and VMware Update Manager May Fail to Upgrade the Update Manager Database
You can use the unified installer to simultaneously upgrade VirtualCenter and VMware Update Manager, but problems with custom database configurations might occur. VirtualCenter and VMware Update Manager can store information in a single database or in separate databases. If your deployment includes separate databases, and you do not use the Custom option during upgrade, the VMware Update Manager database might not be upgraded. Instead, one of two things might happen:- If there is no Update Manager database in the VirtualCenter database instance, a new Update Manager database is created.
- If there is an existing but unused Update Manager database, it is upgraded. Unused Update Manager databases might exist when an initial installation is completed and then subsequently a separate Update Manager database is established.
To avoid this issue, select the Custom type for the installation and specify the Update Manager database that your deployment is using.

VMware High Availability (HA)
-
Some failed virtual machines are not powered on on the default failover host
During HA failover, some failed virtual machines are not powered back on on the default failover host. This happens because the das.defaultfailoverhost setting does not take effect.
Workaround: - Specify the das.defaultfailoverhost in the VI Client and reconfigure cluster.
- In the VI Client, click Hosts & Clusters.
- Right-click a cluster and select Edit Settings.
- In the <Cluster_name> Settings page, select VMware HA and click Advanced Options.
- Enter das.defaultfailoverhost in the Option field and the IP address or host name of the default failover host in the Value field.
- Click OK to reconfigure the cluster.
- Reconfigure all hosts that failed earlier and rejoined the cluster.
- In the VI Client, click on Hosts & Clusters.
- Select a cluster, and click on the Hosts tab.
- Select all the hosts to be reconfigured, right-click and select Reconfigure for VMware HA.
-
Virtual Machines Using a NFS Datastore Might Fail After an HA Failover Event
When you have memory overcommitment with virtual machines on a NFS datastore, it results in the creation of a vswp file, which is a non-zero size swap file. In this scenario if HA failover events occur and the HA has the setting Leave VM powered on, then you might have a virtual machine failure on the host where the virtual machine was originally running before the HA event.
If you do not have memory overcommitment with virtual machines on a NFS datastore, if HA failover events occur with the setting Leave VM powered on, further migration of the virtual machine running on the original host might fail.
Workaround: Apply Patch ESX350-200905401-BG to ESX Server 3.5 hosts, and Patch ESXe350-200905401-I-BG to ESX Server 3i version 3.5 hosts.
-
When a Virtual Machine Running on a NAS Datastore Is Configured to Be Shut Down or Left Powered On in Response to Host Isolation, the Virtual Machine Might Attempt to Run Simultaneously on Two Hosts in a Network Isolation Event
In the event of a multiple network failure that causes host isolation and the loss of network access to the datastore, if a virtual machine is configured with the setting Shut down VM or Leave VM powered on in case of host isolation, the virtual machine might fail to respond indefinitely. Because HA tries to power off the virtual machine and restart it on another host, two instances of the virtual machine might appear in the VI Client. There is no data corruption, because HA and VMFS correctly control access to the virtual machine's data, but the original virtual machine becomes non responsive. After access to the datastore is restored on the isolated host, the original virtual machine can be manually powered off.
Workaround: In NFS or iSCSI environments, select Power off VM as the default virtual machine response in a cluster if a host is isolated. -
In an HA Cluster That Contains Around 80 Virtual Machines Per ESX Server Host Virtual Machines Might Not Fail Over to Other Hosts
Starting with the VirtualCenter 2.5 Update 5 release, in an HA cluster, an ESX Server host can support up to 80 virtual machines. With around 80 virtual machines running on every ESX Server host in an HA cluster, if hosts within the failover capacity limit fail, it might be observed that not all virtual machines are powered on other hosts in the cluster. VirtualCenter Server might display messages similar to the following:
HA agent on <ESX_Server_Name> in cluster <Cluster_Name> in <DataCenter_Name> has an error
The log files might display messages similar to the following:
Could not power on VM : Number of running VCPUs limit exceeded
This issue occurs when the limit of virtual CPUs per ESX Server is not increased to 192. Since the ESX Server 3.5 Update 1 release, the limit for the number of virtual CPUs per ESX Server is raised from 128 to 192. By default, this limit is still set to 128 for an ESX Server host. To resolve the issue, increase the virtual CPU limit to 192 for each ESX Server in the HA cluster.
For information on increasing the virtual CPU limit for an ESX Server host, see Limit of Virtual CPUs Raised from 128 to 192 on ESX 3.5 Update 1 and Later Updates. (KB 1006393) - Edited Advanced Options In an HA-Enabled Cluster Do Not Take Effect (KB 1008479)

VMware HA Health Monitoring Does Not Show Rebooting in the Console After a Host Failover
After a host failure, the virtual machine console displays an empty window when health monitoring is enabled for an HA cluster. The console does not display the virtual machines rebooting.
Workaround: You must open a new console window to see the virtual machines restarting after the failover. -
VI Client Might Show the Host as Not Responding During HA-DRS Cluster Operations
During HA-DRS cluster operations such as adding or removing a host from a DRS cluster or applying DRS recommendations, the VI Client might show the host as Not responding, even when the host IP can be reached.
Workaround: Disconnect the host from the HA-DRS cluster and reconnect it. This refreshes the system, and the VI Client reflects the configuration changes that you have made. If the VI Client again shows the host as Not Responding, disconnect the host from the HA-DRS cluster, remove the host, and add the host back to the same cluster. -
Reconfiguration of HA Agent on an ESX Server Host Might Fail After VirtualCenter Server Is Upgraded
When a VirtualCenter Server that contains an HA-enabled cluster is upgraded, and ESX Server hosts are reconnected to the VirtualCenter, reconfiguring the HA agent of one of the ESX Server hosts might fail with an HA agent error message similar to the following:
HA agent on <Host_Name> in cluster <Cluster_Name> in <Datacenter_Name> has an error:
cmd addnode failed for primary node: /opt/vmware/aam/bin/ft_startup failed
Workaround: After upgrading the VirtualCenter Server, disable and re-enable HA on the cluster. -
HA network compliance check
During the configuration of HA in VirtualCenter 2.5 Update 2, the Task & Events tabs might display the following error message and recommendation:
HA agent on <esxhostname> in cluster <clustername> in <datacenter> has an error Incompatible HA Network:
Consider using the Advanced Cluster Settings das.allowNetwork to control network usage.
Starting with VirtualCenter 2.5 Update 2, HA has an enhanced network compliance check to increase cluster reliability. This enhanced network compliance check helps to ensure correct cluster-wide heartbeat network paths. See KB 1006606 for details. - VM Monitoring feature in VMware HA is not supported for ESX or ESXi releases prior to ESX 3.5 Update 3
With VMware HA enabled for a cluster managed by VirtualCenter Server 2.5 Update 6, the VM Monitoring feature does not function correctly on ESX or ESXi hosts older than ESX 3.5 Update 3 and might cause false virtual machine failovers.
Workaround: Disable the VM Monitoring feature for those VMs or upgrade the ESX/ESXi host to ESX 3.5 Update 3 or later.
