I have a working LAMP virtual machine. I can use it for as long as I want with no problems. However as soon as I reboot, the entire file system goes into read-only and I am unable to do anything.
I have a snapshot I keep reverting back to so I can continue using the machine, but no matter what, the next time I shutdown or reboot everything goes to read-only.
The only changes worth noting since the last snapshot (from a long time ago):
-www-data was added to the dialout group
-I configured a serial port with COM4
