8.1 Problems with installing/uninstalling the EWLM code
INST Problem
Problem reinstalling the IBM Virtualization Engine.
Error received
No specific error message is received. The previous message received was:
The IBM Virtualization Engine uninstaller has successfully completed.
Expanded description
After uninstalling the IBM Virtualization Engine and trying to reinstall it we ran into a problem
where the new install could not install using the same default VE directory (directory already
exists).
Diagnosis and solution
We navigated to the default directory for IBM VE and it still existed. This is because the
uninstall Virtualization Engine wizard does not remove the VE directory or driver, even though
it says it does. We manually deleted the directory /opt/IBM/VE and ran the IBM VE install
again using the wizard. This time we were successful.

Expanded description
When we installed the EWLM code on our machines using the VE Installation Wizard, we
specified the IBM Virtualization Engine install directory as /ewlmdm. Although the installation
ran successfully, when we tried to use the directory (by issuing the createDM command, which
in turn was creating the WebSphere Application Server on the Linux machine), we received
the error described.
