Development Steps
Host architecture
- Directory structure & Initial Set-up (Pre-Installer Work Envinonment)
QEMU
Extracted files from downloaded file, 'qemu-0.8.2-windows.zip' Directory 'qemu-0.8.2-windows' is produced when extaction is complete Moved 'qemu-0.8.2-windows' directory to 'C:\Program Files\qemu-0.8.2-windows'
QEMU Accelerator Module
Extracted files from downloaded file, 'kqemu-1.3.0pre9.tar.gz' Directory 'kqemu-1.3.0pre9' is produced when extaction is complete Moved 'kqemu-1.3.0pre9' directory to 'C:\Program Files\kqemu-1.3.0pre9' Right click on 'kqemu.inf' and select 'Install' from pop-up menu
VA VistA Demo Toaster 20060926
Extracted files from downloaded file, 'VAVistADemo20060912.zip' File 'xxxx' is produced when extaction is complete Moved 'xxxx' directory to 'C:\Program Files\qemu-0.8.2-windows'
- Guest launch scripting
Modifications: qemu-win.bat
The .bat file that comes with QEMU has been modified to launch Toaster.
The original file:
REM Start qemu on windows. @ECHO OFF REM SDL_VIDEODRIVER=directx is faster than windib. But keyboard cannot work well. SET SDL_VIDEODRIVER=windib REM SDL_AUDIODRIVER=waveout or dsound can be used. Only if QEMU_AUDIO_DRV=sdl. SET SDL_AUDIODRIVER=dsound REM QEMU_AUDIO_DRV=dsound or fmod or sdl or none can be used. See qemu -audio- help. SET QEMU_AUDIO_DRV=dsound REM QEMU_AUDIO_LOG_TO_MONITOR=1 displays log messages in QEMU monitor. SET QEMU_AUDIO_LOG_TO_MONITOR=0 qemu.exe -L . -m 128 -hda linux.img -soundhw all -localtime
The modified file:

Client connection configuration
CPRS Connection CPRS can connect to the appliance from the host with "CPRSChart s=localhost p=9297 CCOW=DISABLE".
- Need to understand where to add the above string.
- Need steps to configure Hosts file (C:\WINDOWS\system32\drivers\etc)
Guest architecture
- Guest loading scripting
- Start up / Shut down (/etc/init.d/)
- Start/stop TaskMan
- Start/stop RPCBroker (or use inetd/xinetd)
- ...
- Start up / Shut down (/etc/init.d/)
If you start Taskman, retrieving data in the background will work for the CPRS client. The Access and Verify codes are VistAis#1 and #1isVistA respectively.
- Can Taskman be start automatically on guest OS boot?
