I'm running an instance of Fedora 16 under VirtualBox (on a Win 7 Pro machine) as a development web server. It's suddenly gone invisible. I have it set to an IP address of 192.168.1.80; I can't ping that address, nor can I find the web pages on it.
I've confirmed that the correct page shows up when I enter "localhost" in a browser running under that virtual machine, and
service httpd status seems to be indicating the httpd server is running properly. What would people recommend I do to investigate/fix this problem?
