Virtual Server

You are currently browsing the archive for the Virtual Server category.

A quick note about g4u – g4u (Ghost for you) is a hard disk imaging tool similar to Norton Ghost, but without the cost. g4u allows you to image hard disks to both files and physical media. This can be accomplished within a physical machine, a virtual machine, or by using an FTP server on either of the two.

In the coming weeks I will be working more on Microsoft’s Windows Vista as it ramps up to release to manufacture (RTM) status.

Although you can currently run Microsoft Virtual Server 2005 in 32 bit mode on a Windows Vista physical machine, I’ve learned that I was recently accepted into the Virtual PC 2007 beta tester program, and that Virtual PC 2007 can run on 64bit Vista.

If you are interested in joining the Virtual PC 2007 beta program, I highly suggest you sign up, then play some fantastic Rod Stewart albums until you are accepted.

By the way, this does in fact mean you can run Vista on Vista reliably now. VMWare Workstation and Server still don’t work at this point, but it’s on the way, just stay tuned.

Continuing on our saga through the undocumented Virtual Server WMI interfaces, we now arrive at disk usage information. Here is a sample script that will create a list of the currently running virtual machines, and display the amount of disk activity they have had since they were powered on.

Set vsWMIObj = GetObject(“winmgmts:\\.\root\vm\virtualserver”)
Set vms = vsWMIObj.ExecQuery(“SELECT * FROM VirtualMachine”,,48)
For Each vm in vms
Wscript.Echo “==============================================”
Wscript.Echo “Virtual machine: ” & vm.Name
Wscript.Echo “MiB read from disk: ” & vm.DiskBytesRead / 1048576
Wscript.Echo “MiB written to disk: ” & vm.DiskBytesWritten / 1048576
Next

As you can see these disk counters usually report values in bytes. It is important to note that these counters are also reset to zero every time the virtual machine is turned off.
