Title:
  Failed to launch new VM after changing "nova.conf" for specifying
  target cpu_model

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  Version: stable/icehouse

  Description:
  Change the Nova config file "nova.conf" for specifying the target cpu_model of Penryn as follows:

  cpu_mode = custom
  cpu_model = Penryn
  virt_type = kvm|qemu

  After that, restart Nova services.

  Eventually, try launching new VM, but it is failed with the following
