6559	Guest OS Loses Network Connection	jwilliams108		Running VirtualBox 3.1.6 on a Mac OS X Server 10.6.3 Host on an XServe, with CentOS 5.4 Guest. The Guest OS loses its network connection (both host-only and nat) within 5-10 minutes of startup. The network appears up, but I cannot access the Guest from the Host, nor can I get out from the Guest to the internet, lan or host machine. Restarting networking within the Guest does not fix the problem, nor does restarting the Guest OS. Saving the VM state and starting it again seems to be the only means of re-establishing network connectivity. I have also noticed, however, that continuous network access (i.e., pinging the guest) seems to keep it accessible. Strangely, this same VM setup works fine on 10.6.3 non-server on a Mac Pro.	defect	closed	network/hostif	VirtualBox 3.2.12	fixed			Linux	Mac OS X
