I have a question regarding Dynamically Expanding Virtual Hard Disk
expanding past the maxium allocated size.

I have had a couple of instances where I had the maxium size set to 16Gb and
24 hours later, the file has grown to over 60 Gb.

Any ideas on hos tih is possible?

Brian,

What are you using to communicate with your virtual server? C# and the
COM interface?

Not sure I totally understand your question.

Here's what's happening.

I have created 2 VHD's, one for the operation system and another for data.
I install w2k3, patches, .net 3.0 framework on the OS drive and sharepoint
server 2007 on the data drive. A couple of days go by and my os drive has
grown an unexpected harddrive size, over 60 gb even thought I created
dynamucally expanding vhd's and set the maxium size to 16gb, how does it
grown far past the maxuim?

I'm using the virtual server admin interface and remote control to
communcate with the virtual server.

Other than the installed software, we have not programmed anything to
communicate with this virtual server.

Does this help?

Sorry, I misunderstood your question.
If I understand correctly, you do not want the vhd to consume more than
16GB right?

Generally this is caused by backup agent software on the host that is
trying to backup your VHD. Excluding VHDs or the VM's directory
usually resolves the issue.

Hi,

Is your host's antivirus monitoring these files? If so, you may consider
disabling the monitoring of .VHD files. Host AVs have been known to cause
VHDs to grow much larger than they should

â€œThe Path To Fast P2Vâ€ â€“ The QuickSilver Project

We all have tons of physical machines we want to migrate to Virtual Hosts,
and we all want to do it in a smooth low administrative cost process.
Well, all we have to do is to use the VSMT right? (Virtual Server Migration
Toolkit). The problem is that its too complex to use it, and in the end the
hours you spend to run all the VSMT process is maybe even bigger than the
one you would take to set it up the hole thing again without VSMT at all!!
This is what I came up after some small researching.
I Managed to P2V in 2 Single Steps, and I would like to share my experience
with you.
Suppose you have a nice Windows 2003 Sp1 Machine running on a old Server,
and you want to P2V it to Virtual Server. Simply you use your cloning
solution of you choise (preferably I use Acronis and Ghost), and deliver the
image to the Virtual machine as it was a physical one.
Logical when the Virtual Machine boots you get a â€œBlue Screen of Deathâ€
because of the hardware Incompatibility.
All you have to do is to boot up the Virtual Machine with the Windows 2003
Sp1 CD, choose the R option to go to the Recovery Console, when you just get
the famous â€œDos Like Consoleâ€
This is the amazing part.. you copy from the CD of Windows 2003 Sp1 the
hal.dll and ntoskrnl.exe and override in the Windows system32 directory.
In simple Commands you do as follows..
1.boot the Virtual machine with the cd of Windows 2003 SP1
2. Press R for the Recovery Console
3. choose your Windows Installation (usually option 1)
Go to windows system32 folder by typping cd c:\windows\system32
Then enter the drive letter of cd-rom (usually dïŠ
At d: prompt type cd i386
Then type as follows
Expand ntoskrnl.ex_ c:
Expand hal.dl_ c:
For each command you will take a notification for overwriting the original
files.. we choose yes to replace the files.

Then rebout the machine, remove the cd-rom of window 2003 sp1, let the
machine boot and press F8 to go to option menu for Safe Boot.
THERE YOU ARE, THE TARGET MACHINE IS BOOTING WITH NO ERRORS.
IT WILL AUTO DISCOVER ALL THE HARDWARE AND IT WILL PLAY OK

100% TESTED, MIGRATED MANY MACHINES LIKE THAT.

PLEASE FEEL FREE TO CONTACT ME FOR ANY INFORMATION YOU MAY NEED.

BEST REGARDS.

Depends on the context.

Did you try either of the suggestions, backup and AV program
exclusion?

How do you know it's not been accepted?

Most of the time the problem that the OP is seeing is caused by what I
posted. this issue has been discussed here before, the same answer I
gave has been given by MS employees who work with VPC.

And is a known cause of this problem, along with AV programs.
