The Oracle VM Manager installer may fail to install Oracle XE and displays the message:
Failed: The database instance is not available.
You can check the log file at /tmp/ovmm-installer.selfextract_id/install-date.log for more detailed information.
Workaround: There are two workarounds to this issue.
Make sure that Oracle XE is not installed, or has installed correctly. Use the following command to check the status:
$ /etc/init.d/oracle-xe status
If an Oracle XE is running, run the Oracle VM Manager installation script to uninstall it, and reinstall Oracle VM Manager.
Make sure the computer's host name matches the host name in the /etc/hosts file. See Section 3.3.2.2, “Network” to configure the host name.
