8:01 am in Uncategorized by mikeresseler

Hey All,

Microsoft has released the Product Support Reporting Tool for SCVMM2008 and 2008R2

Use the MPS Reporting Tool to gather detailed system status and configuration information from the Virtual Machine Manager server of Virtual Machine Manager 2008 or 2008 R2 server as well as from all managed virtual machine hosts, library servers, and physical to virtual conversion (P2V) source computers. This version of the MPS Reporting Tool collects gathers data to help Microsoft Support Professionals diagnose error conditions experienced in Microsoft System Center Virtual Machine Manager 2008 and Microsoft System Center Virtual Machine Manager 2008 R2.
The Virtual Machine Manager (VMM) version of the MPS Reporting Tool gathers the following diagnostic data for the VMM server, the virtual machine hosts and library servers that the VMM server manages, and physical to virtual conversion (P2V) source computers:

  • Virtual Machine Manager traces
  • Virtual Machine Manager database
  • Windows event logs and virtual server event logs
  • IP address
  • Virtual Machine Manager setup logs
  • SQL Server setup logs
  • Registry information
  • Open ports information
  • System Information (msinfo)

You can download the tool here: http://www.microsoft.com/downloads/details.aspx?FamilyID=4e3dc013-c299-4b80-9735-64a8b9fa60c7&displaylang=en

System Center Virtual Machine Manager: Hosts having 0kb free memory

5:24 pm in Uncategorized by mikeresseler

Hey All,

One of the big issues with SCVMM 2008 for me was that the memory available on the hosts is not correct.  If you are running quite a large environment with a lot of virtual machines, it is difficult to know how many you have left.  You can of course start calculating it manually but… 😉

So here’s a screenshot of the problem

image

As you can see, all my hosts are giving zero kb free of memory.  That’s not exactly correct

Here’s how to solve this one:

On each host that has this problem, open the registry and go to the following key:

HKLM\SYSTEM\CurrentControlSet\Services\PerfOS\Parameters

If you see the key “Disable Performance Counters” then change it to 0.

Now you need to restart the WMI service on the host.  Please pay attention because it will restart other services too and you don’t want to do this during production hours…

After that the services are restarted, you can refresh your configuration in SCVMM and then you get the correct figures

Virtual Machine Manager 2008: Cost Center

10:21 am in Uncategorized by mikeresseler

Hey All,

One of the nice things in Virtual Machine Manager is the Cost Center feature.  Although this seems like “just another field in the database”, it can come in handy when you need to prove to your management which business unit is using what resources.  Or, if the servers are used for certain projects, you can prove which project is using what.  This can be handy when you need more hardware and the management asks a prove if you are using everything you’ve got 😉

In my example, I’ve added some cost centers to some servers.  You do this by double-clicking on the virtual server or by opening the properties of it.

image

As you can see, I’ve added the Cost Center MSS to this server (which is actually the business unit I’m working for ;-))

Now the fun starts when you have Operations Manager in place and you have imported the Virtual Machine Manager Management Pack into OpsMgr.  Now you get cool reporting.

In Virtual Machine Manager, I go to reporting and I have one interesting report called Virtual Machine Allocation

image

Ok, I hid the names of the cost centers but the important thing is that you can see that for each cost center I can see the # of VM’s, # of VM’s deployed, # in the library, # of processors, total allocated memory, number of disks, max disk space allocated and the number of nics.

Now the management has a great overview of who’s using all the hardware resources within the company.

Cheers,

Mike
