So in order to prevent this you could change the location of the VPXD log files very easily. Edit “vpxd.cfg”. It’s located here: %AllUsersProfile%\Application Data\VMware\VMware VirtualCenter\.

Add the following lines in the “<config>” section and change the path accordingly:

<log>
<directory>c:\VC_Logs</directory>
</log>

Shutdown VM requires VMware Tools to be installed. If HA is unable to shutdown the VM within 5 minutes it will be powered down. I would prefer this option, especially when you virtualized services like Exchange, SQL, Oracle etc.

VirtualCenter 2.5 already contained a feature called “Distributed Power Management”, with this feature the VirtualCenter database became more important but still one could easily do without it. But VMware just released VirtualCenter 2.5 Update 2. This update contains a new feature for HA. HA will get it’s IP info straight from VirtualCenter instead of the /etc/hosts file or DNS. With this info HA fills up /etc/FT_HOSTS. This all of a sudden makes the VirtualCenter database and the VirtualCenter server more important than ever.

I guess it’s time to start building the VirtualCenter server in a different way. Going virtual might be the best solution for having a highly available VirtualCenter server and database. But what about actually backing up the Database, via a maintenance plan or a backup engine. In time the VirtualCenter database will only get more important, especially when for instance DPM evolves. I can imagine DPM will detect trends and switch servers on and off accordingly.

Anyway, the only message I wanted to get out is start backing up that database!

How do I do this:

1. click on scheduled tasks
2. click new and pick “import a machine”
3. select “physical” and enter the servers name/ip and username and password
4. select the disks you want to import
5. type a name for the VM
6. select the destination host
7. select a datastore
8. select a network
9. and schedule the task!

Besides “Power Off” and “Leave powered on” there’s a new option introduced. And this is one I was looking for, “Shutdown VM”. Shutdown VM doesn’t just pull the cord, it tries to shutdown the VM in a decent fashion, via the OS.

So what’s new?

• Windows Server 2008 support – Windows Server 2008 (Standard, Enterprise, and Datacenter editions) is supported as a guest operating system. With VMware’s memory overcommit technology and the reliability of ESX, virtual machine density can be maximized with this new guest operating system to achieve the highest degree of ROI. Guest operating system customizations and Microsoft Cluster Server (MSCS) are not supported with Windows Server 2008.
• Enhanced VMotion Compatibility – Enhanced VMotion compatibility (EVC) simplifies VMotion compatibility issues across CPU generations by automatically configuring server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers. Once EVC is enabled for a cluster in the VirtualCenter inventory, all hosts in that cluster are configured to ensure CPU compatibility for VMotion. VirtualCenter will not permit the addition of hosts which cannot be automatically configured to be compatible with those already in the EVC cluster.
• Storage VMotion – Storage VMotion from a FC/iSCSI datastore to another FC/iSCSI datastore is supported. This support is extended on ESX/ESXi 3.5 Update 1 as well.
• VSS quiescing support – When creating quiesced snapshot of Windows Server 2003 guests, both filesystem and application quiescing are supported. With Windows Server 2008 guests, only filesystem quiescing is supported. For more information, see the Virtual Machine Backup Guide and the VMware Consolidated Backup 1.5 Release Notes.
• Hot Virtual Extend Support – The ability to extend a virtual disk while virtual machines are running is provided. Hot extend is supported for vmfs flat virtual disks without snapshots opened in persistent mode.
• 192 vCPUs per host – VMware now supports increasing the maximum number of vCPUs per host 192 given that the maximum number of Virtual Machines per host is 170 and that no more than 3 virtual floppy devices or virtual CDROM devices are configured on the host at any given time. This support is extended on ESX 3.5 Update 1 as well.

I really really like the VSS support for Snapshots, especially for VCB this is a great feature! And what about hot extending your harddisk, this makes a VMFS datastore as flexible as a RDM datastore!

For Hardware there are also a couple of really great additions:

• 8Gb Fiber Channel HBAs – Support is available for 8Gb fiber channel HBAs. See the I/O Compatibility Guide for ESX Server 3.5 and ESX Server 3i for details.
• SAS arrays – more configurations are supported.  See the Storage/SAN Compatibility Guide for ESX Server 3.5 and ESX Server 3i for details.
• 10 GbE iSCSI initiator – iSCSI over a 10GbE interface is supported. This support is extended on ESX Server 3.5 Update 1, ESX Server version 3.5 Update 1 Embedded and ESX Server version 3.5 Update 1 Installable as well.
• 10 GbE NFS support – NFS over a 10GbE interface is supported.
• IBM System x3950 M2 – x3950 M2 in a 4-chassis configuration is supported, complete with hardware management capabilities through multi-node Intelligent Platform Management Interface (IPMI) driver and provider. Systems with up to 32 cores are fully supported.  Systems with more than 32 cores are supported experimentally.
• IPMI OEM extension support – Execution of IPMI OEM extension commands is supported.
• System health monitoring through CIM providers – More Common Information Model (CIM) providers are added for enhanced hardware monitoring, including storage management providers provided by QLogic and Emulex.  LSI MegaRAID providers are also included and are supported experimentally.
• CIM SMASH/Server Management API – The VMware CIM SMASH/Server Management API provides an interface for developers building CIM-compliant applications to monitor and manage the health of systems.  CIM SMASH is now a fully supported interface on ESX Server 3.5 and VMware ESX Server 3i.
• Display of system health information – More system health information is displayed in VI Client for both ESX Server 3.5 and VMware ESX Server 3i.
• Remote CLI – Remote Command Line Interface (CLI) is now supported on ESX Server 3.5 as well as ESX Server 3i. See the Remote Command-Line Interface Installation and Reference Guide for more information.

One of the important thing in my opinion is the full support for the CIM Smash API! And iSCSI over a 10GBe interface, same goes for NFS! 8GB fibre and SAS arrays is a great extension.

• VMware High Availability – VirtualCenter 2.5 update 2 adds full support for monitoring individual virtual machine failures based on VMware tools heartbeats. This release also extends support for clusters containing mixed combinations of ESX and ESXi hosts, and minimizes previous configuration dependencies on DNS.
• VirtualCenter Alarms – VirtualCenter 2.5 Update 2 extends support for alarms on the overall health of the server by considering the health of each of the individual system components such as memory and power supplies. Alarms can now be configured to trigger when host health degrades.
• Guided Consolidation – now provides administrators with the ability to filter the list of discovered systems by computer name, IP address, domain name or analyzing status. Administrators can also choose to explicitly add physical hosts for analysis, without waiting for systems to be auto-discovered by the Consolidation wizard. Systems can be manually added for analysis by specifying either a hostname or IP address. Multiple hostnames or IP addresses, separated by comma or semi-colon delimiters, may also be specified for analysis. Systems can also be manually added for analysis by specifying an IP address range or by importing a file containing a list of hostnames or IP addresses that need to be analyzed for consolidation. Guided Consolidation also allows administrators to override the provided recommendations and manually invoke the conversion wizard.
• Live Cloning – VirtualCenter 2.5 Update 2 provides the ability of creating a clone of a powered-on virtual machine without any downtime to the running virtual machine. Therefore, administrators are no longer required to power off a virtual machine in order to create a clone of it.
• Single Sign-On – You can now automatically authenticate to VirtualCenter using your current Windows domain login credentials on the local workstation, as long as the credentials are valid on the VirtualCenter server. This capability also supports logging in to Windows using Certificates and Smartcards. It can be used with the VI Client or the VI Remote CLI to ensure that scripts written using the VI Toolkits can take advantage of the Windows credentials of your current session to automatically connect to VirtualCenter.

One of the best new features described above in my opinion is the extension of Alarms! It’s awesome that VirtualCenter will report on hardware health! But what about that live cloning, that will definitely come in handy when troubleshooting a live production environment. Just copy the server, start it without the network attached and try to solve the problem!

Ran into a problem while doing some performance testing on some test VMs. We found that we had no historical performance data for the VM or Host. All we had was real time data. This can be a major issue, especially when you are trying to troubleshoot or like in this case get performance data for a performance test! My co-worker did some research and found that we are not an isolated event. This is a bug in VC 2.5.

The Fix

We found a few references to doing a “repair” install of VC 2.5. So we went ahead and tried it and it worked. We also found references to the performance data getting corrupted. In that case they had to restore the database to a prior dataset and re-install the VC.

I’ve seen the same at several customer sites and indeed the fix that Clint describes, repair of VirtualCenter, works.
