CONFIG_VIRT_CPU_ACCOUNTING=y
CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y
# CONFIG_VIRT_CPU_ACCOUNTING_GEN is not set

I created two VMs and watched top in each VM and observed a steal%.

Title:
  Enable CONFIG_VIRT_CPU_ACCOUNTING_NATIVE for ppc64el

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Utopic:
  Fix Committed

Bug description:
  [Impact]
  I would like to ask to set  CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y on ppc64el kernel config in 3.16 kernel (14.10 and/or 14.04.2) to provide %steal number properly reported.

  Historically, it was enabled, became disabled and later enabled again:

  Ubuntu 14.04:
  # cat /boot/config-3.13.0-24-generic | grep VIRT_CPU
  CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y

  Ubuntu 14.10:
  # cat /boot/config-3.16.0-23-generic | grep VIRT_CPU
  # CONFIG_VIRT_CPU_ACCOUNTING_NATIVE is not set

  Ubuntu 15.04:
  # cat /boot/config-3.19.0-12-generic | grep VIRT_CPU
  CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y

  [Test Case]
  Run VM and ensure %steal is reported properly.

  [Fix]
  CONFIG_VIRT_CPU_ACCOUNTING_NATIVE=y in config.
