The "disk" was an ordinary file. The write timed out so Linux (the same Ubuntu 12.04) perceived it as a disk failure and remounted read-only. There were no physical hardware errors involved. It caught me by surprise when it happened and it took a little bit until I understood what's going on. The system just behaved weird (it was only one of three virtual disks so the system worked partially) I have a nagios/Icinga script checking the expected mounts since then. It compares the mounts with a mount "snapshot" written in a file after installation.
