I then have to power off and power on again the VM. I've been using this guest VM for several months with older versions of Virtualbox (but also running earlier versions of Ubuntu) and never had this issue. The VM log (see attachment) doesn't seem to contain any relevant information." defect closed other VirtualBox 4.0.8 obsolete Windows Linux
