Ubuntu 15.10 on VirtualBox stuck on login screen

[Luca Ciavatta]

I'm trying to test Ubuntu 15.10 (http://cdimage.ubuntu.com/ubuntu-desktop-next/daily-live/current/wily-desktop-amd64.iso) on a VirtualBox virtual machine. Installation process has gone well and I can start the vm. I can see some issues on the boot process and after the login screen comes. In the login screen, I can insert the password but after I did the screen stuck and I can only the icon to shutdown or restart the system. I have also tried to enter as guest, but the result is the same. Moreover the key combinations ctrl+alt+F1, F2, F7 gave me only to a black screen with a flashing cursor and no terminal shell. I have tried to change some value on the vm configuration, but nothing happens.

On boot process, the screen shows:
ACPI PCC probe failed
piix4_smbus 0000:00:07.0: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr
intel_rapl: no valid rapl domains found in package 0

I have tried to install Ubuntu 15.10 (the same file of the same image) on VirtualBox on another host machine. A part some message during the first restart, all went perfect and the system works like a charm. I think the problem above is made by the host machine and not by Ubuntu guest.

First host machine: MacBook Pro 8,2 running Fedora 22 with VirtualBox 5.
Second host machine: Xeon 3360 Radeon HD5450 running Ubuntu 15.04 with VirtualBox 5.

VirtualBox with the same settings.

which machine is broken and which works?

[Luca Ciavatta (cialu)]

Problem happens on VirtualBox on Fedora 22.
On Ubuntu 15.04, Ubuntu 15.10 virtual machine works like a charm.

[Gianfranco Costamagna (costamagnagianfranco)]

lol if the problem is on fedora I can't do anything on the Ubuntu side :)

I suggest you to open a fedora bug or an upstream ticket

I enabled enable PAE/NX on Virtualbox, and it allowed the installed ubuntu 15.10 to continue booting
