To access services from the qemu client os from a microsoft os instance running qemu you can start a batch file containing

gistfile1.bat

@echo off

pushd %qemudir%
:: This call is an example only, customize the paths:
call :start_the_machines "d:/grml_2009.05.iso" "d:/basehd.qc2" "d:/lvmhd.qc2"
goto :eof

:: start_the_machines isofile hdimage1 hdimage2
:start_the_machines %1 %2 %3
set hdX=-drive file=%2,index=0,media=disk -drive file=%3,index=1,media=disk
set srX=-drive file=%1,index=2,media=cdrom
set netopts=-net nic -net user,hostname=mywebserver
:: assume host is running a qemu instance with an OS image - the client - running inside it

:: out for readability)
