Just saw two variations of this with Ubuntu Studio amd64 and Virtual Box on two different sets of host hardware (desktop and laptop).
Laptop: Reached the end of the full installation, and got the "Installation complete - you need to restart" dialogue. Clicked to restart and the VM froze with the dialogue showing that I had clicked the button for at least half an hour. Walked away, and when I came back, the VM had booted into the installed Ubuntu Studio. So a pass, but frustratingly slow. Desktop: Reached the end of the full installation, and got the "Installation complete - you need to restart" dialogue. Clicked to restart and the VM slowly removed icons, then went to a blank screen, and hung for at least half an hour. Walked away, and when I came back, the VM had booted into the live Ubuntu Studio installation ISO again. Chose shutdown from the menu, and I am still waiting for the machine to shutdown 20 minutes later. ** Attachment added: "VirtualBox_UbuntuStudioXenial1604_23_03_2016_14_59_06.png" https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1447038/+attachment/4608656/+files/VirtualBox_UbuntuStudioXenial1604_23_03_2016_14_59_06.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1447038 Title: Shutdown/Restart of live session guest does not work in Virtualbox, and VMWare To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/1447038/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
