The issue it turns out isn&#8217;t a VMware issue &#8211; it&#8217;s an Oracle bug when running 32-bit 11gR2 client on a 64-bit RH OS with an AMD processor.  The fix is Oracle patch 8670579.<\/p>\n<p>KB Article: 1023898 <a href=\"http:\/\/kb.vmware.com\/selfservice\/search.do?cmd=displayKC&amp;docType=kc&amp;externalId=1023898\"><br \/>\nRedHat and CentOS virtual machine show warning messages when starting the udev daemon<\/a><\/p>\n<p>This issue actually cropped up in my VMware environments awhile ago.

The issue occurs because VMware tools configuration is looking for the 64-bit tools (64-bit OS, generally you&#8217;d want to install the 64-bit RPMs&#8230;).
