Beginning of February 2014 I moved back from goPivotal to EMC.
Whenever you Copy&Paste (or Cut&Paste) something into or from a VMware instance, the software first copies the files into a temporary directory and later on sends the copy/move job to Windows. Since the Windows task is asynchronous, VMware has no chance to find out when this actually finishes - so it is supposed to clean up this temporary directory at boot time.
However, waiting for the next reboot can clog up quite some disk space (when I develop something I often have to copy many files around between several virtual machines and the desktop) - despite that Windows still likes to BSoD on me from time to time. And sometimes VMware does not get the cleanup right at reboot and the files are still there.
If you download the Greenplum Community Edition (GP CE) from the Greenplum website and if you want to connect tools like pgAdminIII from your host machine to the database inside the virtual machine, you have to disable the firewall. The CE is installed on CentOS and by default the firewall is enabled and blocks connections from outside to most ports.
Here are the steps which are required to disable the firewall:
Just installed a small CentOS 5 without additional packages and the 4 GB VMWare disk is almost full :-(
