Hi!

Is mini-problem [, IMHO]

See example of real problem:


> changed the Kconfig symbol to CONFIG_HYPERVISOR_GUEST on x86.

And when CONFIG_HYPERVISOR_GUEST not set ( IMHO, not special) , as result

linux-mainline ( non-official, but very usefull) v3.10-rc1 2013-05-12 for Arch Linux

not contain

hv_storvsc.ko.gz

as not contain (

hv_vmbus.ko.gz
hv_utils.ko.gz
hv_netvsc.ko.gz
hv_balloon.ko.gz


)

Arch Linux linux-mainline v3.9 contain all this files

i.e. not only "balloon driver[s]"
