This is a set of best practices to follow when installing a Windows 2003 guest on a Proxmox VE server.  Right now it's a work in progress, written by a Proxmox noob but hopefully soon it will be a comprehensive and reliable document.  Please feel free to add to it, even if just to pose a potential best practice.

===UNTESTED: caching===
Under disk properties in Windows 2003 you can turn off the disk cache (Windows caches writes in ram). KVM enables it's own writethough caching which relies on the Debian hosts caching (I think). Plus modern disks have a sizable hardware cache. Do we really need all this chained redundant caching?
 
With VIRTIO the system sees the DEV as a USB so the way to turn off caching is:
Computer Mgmt -> Disk Mgmt -> Select Drive (system) -> properties -> Hardware -> VirtIO Drv -> Properties -> Policies -> Optimize for quick removal
 
===UNTESTED: sparse disk===
Use a utility like [http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx SDelete] to zero out a drive and take advantage of ext3's sparse file handling.

Introduction

This is a set of best practices to follow when installing a Windows 2003 guest on a Proxmox VE server. Right now it's a work in progress. Please feel free to add to it, even if just to pose a potential best practice.

Disk

raw vs qcow2

Raw file format provides better performance while qcow2 offers advanced features such as copy on write and snapshots.

virtio storage drivers

Use virtio dirvers for best performance. See http://pve.proxmox.com/wiki/Paravirtualized_Block_Drivers_for_Windows

Note: the latest VirtIO iso do not include drivers for Windows 2003. You need to download an older version.

Network

E1000 NIC

Use e1000 NIC. It's stable and performs well. BUT only with the latest drivers from Intel, download from intel.com! (If you use the integrated drivers, the device manager shows a working NIC, but it does not.)

Windows Server 2003 R2 SP2 ships with drivers that do work, but the ones from intel are newer.

Virtio

Use virtio driver as these are kept updated by Fedora virtio NIC drivers need to be loaded post install & can be found here : https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/latest-virtio/ Information on install can be found here : http://pve.proxmox.com/wiki/Paravirtualized_Network_Drivers_for_Windows

Note: the latest VirtIO iso do not include drivers for Windows 2003. You need to download an older version.

Packet Capture Fix

I highly recommend to add this regfix http://www.intel.com/support/de/network/sb/cs-005897.htm (http://www.intel.com/support/network/sb/CS-005897.htm?wapkw=%284D36E972%29 in english). HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\00xx where you need to search for your network card an add a DWORD "MonitorModeEnabled"="1". ControlSet001 can be CurrentControlSet.

KVM Network Performance

Apply the changes mentioned on the KVM Windows TCP/IP Performance page.

Miscellaneous hints

Power management

  • In order for the Windows 2003 guest to shutdown cleanly in the event of a shutdown on the Proxmox VE host you need to:
  1. enable (Start -> Run -> secpol.msc -> "Security Settings\Local Policies\Security Options")
    1. "Shutdown: Allow system to be shut down without having to log on".
    2. "Interactive logon: Do not require CTRL+ALT+DEL"
  2. disable logon screen screensaver using regedit

REGEDIT4

[HKEY_USERS\.DEFAULT\Control Panel\Desktop]
"ScreenSaveActive"="0"

  • Optional: It may also be useful to set Shutdown Warning Dialog Timeout. This can be done with the following .reg file

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows]
"ShutdownWarningDialogTimeout"=dword:00000001

Alternatively you can you can use the following adm template to apply it via GPO

CLASS MACHINE
	CATEGORY "otherSystem"
	KEYNAME "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows"
		POLICY "Shutdown Warning Dialog Timeout"
		KEYNAME "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows"
		VALUENAME "ShutdownWarningDialogTimeout"
		VALUEON NUMERIC 1
		VALUEOFF DELETE
			PART "Shutdown Warning Dialog Timeout" NUMERIC
			KEYNAME "SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows"
			VALUENAME "ShutdownWarningDialogTimeout"
			REQUIRED
			MIN 0
			MAX 9999
			DEFAULT 1
			END PART
		END POLICY
	END CATEGORY
CLASS USER

NOTE: For this policy to be visible in the Group Policy Object Editor the Only show policy settings that can be fully managed filter must be unchecked.

Clock Drift

If you have any problems with the time on your VM drifting, please see the Guest Time Drift document.
