Hi, Michal

The PES mainstream team identified that it has a higher probability
happend, if the user runing the emulator on a virtualzation disabled
machine.

The user does not even get the panel / welcome screen / greeter, the
whole "screen" of the emulator is blank. It comes back *sometimes* if
restart unity8 by

  $ kill -9 $(pidof unity8) $(pidof unity8-dash)

Here is my theory - When disabled virtualzation in emulator, the system
will be running very slow, and it's possible incrase odds for a race
condition of the unity8/unity8-dash.

Reference -
The developer need to have VT-X/AMD-V hardware for the emulator, and it need to be enabled from BIOS to have better
emulator performance.

The developer can check with the following command -
  # check if the hardware support virtualzation
  $ grep -e svm -e vmx /proc/cpuinfo
  # check if it's enabled from BIOS
  $ sudo apt-get install cpu-checker && kvm-ok

Title:
  unity8 display blank in emulator, host utopic, rtm-14.09 instance.

Status in unity8 package in Ubuntu:
  Confirmed

Bug description:
  As run emulator, device screen is blank.

  Step to reproduce:

  1. install utopic.
  2. sudo add-apt-repository ppa:ubuntu-sdk-team/ppa
  3. sudo apt-get install ubuntu-sdk
  4. launch ubuntu-sdk and install chroot:click-ubuntu-sdk-14.10-armhf, and chroot:click-ubuntu-sdk-14.10-i386
  5. create device instance i386 / rtm-14.09 and launch it.

  Expected result:
  See ubuntu phone UI there.

  Current result:
  Emulator screen is black.

  Extra Note:
  1. On the pc, in the first run of the instance, I can see phone interface on first boot after I "kill -9 unity8 unity8-dash".
      But this work around failed as I stop the instance and run again. I even create the same instance with the other name
     and try this work around, still can't see anything on the screen.
  2. I can run test_glesv2 and see the result on the screen of the display correctly.
