** 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.
