Microsoft, Red Hat to Offer Joint Technical Support

Posted by: Michael Khanin
hypervisors, RHEL, virtualized

Microsoft and Red Hat announced this morning that they have recently signed agreements to test and validate their server operating systems running on one another’s hypervisors. This is deeply significant as it means that customers will be able to confidently deploy Windows Server and Red Hat Enterprise Linux (RHEL), virtualized on Microsoft and Red Hat hypervisors, knowing that the solutions will be supported by both companies.

In short, Red Hat has joined Microsoft’s Server Virtualization Validation Program, and Microsoft is now a Red Hat partner for virtualization interoperability and support. Microsoft will also be listed in the Red Hat Hardware Certification List once the Red Hat certification process has been completed later this year.

Posted by: Michael Khanin
Booting from a .VHD, Windows 7 Booting

If you want to boot from a Windows 7 (Windows Server 2008 R2) installed on a new .VHD do the following steps:

A.-  Creating the .VHD file and Windows 7 installation on that .VHD file

  1. Boot the machine using the Windows 7 DVD
  2. Choose Windows Repair
  3. Start CMD
  4. Run Diskpart
  5. Type: Create vdisk file=c:\Windows7Build7000.vhd maximum=40000
  6. Type: select vdisk file=c:\Windows7Build7000.vhd
  7. Type: attach vdisk (in previous Betas, it was ‘surface’ instead of ‘attach’)
  8. Type: ‘exit’ (you exit Windows Repair, but Do Not Reboot)
  9. Install Windows 7 to this attached .VHD (From Win7 installation, you now have to ‘see’ another Hard Drive, you’ll need to create a partition & format it, first. You might get an error/warning saying that your computer hardware might not support this disk, just ignore it..).
  10. Reboot, and you ready to go!

Find MAC Address (GetMac)

Posted by: Michael Khanin
Find MAC Address, getmac

GetMAC provides a quick method for obtaining the MAC (Ethernet) layer address. I’ve created a small script that rerurens a MAC address (Without delimeter). Here is a content of mac.bat:

@Echo off
SET Media=Connected

FOR /F “Tokens=3 Delims= ” %%a in (‘getmac^|find “Media”‘) do set Media=%%a

IF /I %Media% == disconnected (
FOR /F “Tokens=1-6 Delims=- ” %%a in (‘getmac^|find “Media”‘) do set MAC=%%a%%b%%c%%d%%e%%f

IF NOT %Media% == disconnected (
FOR /F “Tokens=1-6 Delims=- ” %%a in (‘getmac^|find “Device\Tcpip_”‘) do set MAC=%%a%%b%%c%%d%%e%%f

@echo %MAC%

Disable IPv6 over all interfaces and prefer IPv4 to IPv6

Posted by: Michael Khanin
Disable IPv6

Personally, i still prefer use IPv4. In Windows Vista and Windows 2008, IPv6 is enabled by default. I’ve created a small script to disable IPv6. Here is a content of my DisableIPv6.bat:

@Echo off
@ECHO Windows Registry Editor Version 5.00 > %TEMP%\DisableIPv6.reg
@ECHO [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters] >> %TEMP%\DisableIPv6.reg
@ECHO “DisabledComponents”=dword:000000ff >> %TEMP%\DisableIPv6.reg
REGEDIT /S %TEMP%\DisableIPv6.reg

How to know when the sysprep image applied to computer?

Posted by: Michael Khanin

I did a very simple script, and I run it once when I apply a new sysprep image, that imports the date, when this particular image was applied to the specific computer. Sometimes this is very important. Here is a content of my script:

@Echo Off
REM **********************************************************************************************************
REM * This script checks a date Image was deployed and import this data into the Registry as Image-Date REM REM **********************************************************************************************************

For /f “Tokens=2 Delims= ” %%a in (‘@DATE /t’) do set IMG-DATE=%%a
Echo Windows Registry Editor Version 5.00 > %TEMP%\IMG-DATE.reg
Echo “Image-Date”=”%IMG-DATE%” >> %TEMP%\IMG-DATE.reg
Reg.exe import %TEMP%\IMG-DATE.reg
Del %TEMP%\IMG-DATE.reg /Q
