** Description changed:

+ SRU justification:
+ 
+ Impact: Xen HVM guests (since around 2.6.36) will by default disable
+ (unplug) the emulated devices in favour of the paravirtualized drivers
+ when support for both is present (module or built-in). This would make
+ Xen installs more complicated (even if we put them into a udeb because
+ they are not getting autoprobed).
+ 
+ Fix: Change the configurations to have those (and the platform driver
+ which is recommended and actually non-configurable in 3.2 and later)
+ built-in.
+ 
+ Testcase: Installing a normal cdimage in HVM mode.
+

+ 
  It allows to load PVHVM domain having xen_platform_pci=1 in python 
hvm-profile.
  Also xen-blkfront and xen-netfront drivers are not included into inird.img on 
ISO disk,
  what requires (at first boot) :-
  (initramfs) modprobe xen-blkfront
  (initramfs) modprobe xen-netfront
  (initramfs) exit
  to continue loading PV-on-HVM domain.
