_Absolutly_ ( as _minimum_ for SlackWare 14.00 ) need backport requested at 2012-06-08(!) :

i.e. need backport to all actual version after 3.1

An earlier commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c ("ata_piix:
defer disks to the Hyper-V drivers by default") broke MS Virtual PC
guests. Hyper-V guests and Virtual PC guests have nearly identical DMI
info. As a result the driver does currently ignore the emulated hardware
in Virtual PC guests and defers the handling to hv_blkvsc [ VVM: in current ver kernel -- hv_storvsc ] . Since Virtual
PC does not offer paravirtualized drivers no disks will be found in the
guest.
One difference in the DMI info is the product version. This patch adds a
match for MS Virtual PC 2007 and "unignores" the emulated hardware.
This was reported for openSuSE 12.1 in bugzilla:

This should also go to the stable tree, shouldn't it ?
At least 3.8, 3.7 and 3.4
In kernel 3.2 used in
-- Ubuntu 12.4.0 LTS ( after 12.4.2 -- 3.5.X)
and
-- Debian 7.0
source code related Hyper-V backported from "vanila" Kernel v3.5 ( and someone from hi versions)
Please, ask Support Teams of Debian and Ubuntu for backport
Best regards, Victor Miasnikov
Blog: http://vvm.blog.tut.by/
P.S.
to To Microsoft Hyper-V for Linux Team:
what are mint phrase:
"LIS (Linux Integration Services) 4.0"
?
If need details -- ask me by e-mail . . .
P.P.S.
Again to To Microsoft Hyper-V for Linux Team:
See on MS Forum topic
"Linux VM literally crashes Hyper-V host server with STOP 0x00020001"
and (or)
please, remember, CVE number
P.P.P.S.
To SUSE Hyper-V for Linux Team:
Olaf, I'm received Yours e-mail msg ( answer on my earler msg)
Thanks for answer
Unfortunately Yours ( SUSE/Novel) Bug-Tracker not opened by IE from Win Srv Edtions
I'm try do it from OpenSUSE v12.3 LiveCD but can not boot from it in Hyper-V VM when "Dynamic memory" turn on
See details on
http://vvm.blog.tut.by/2013/05/18/opensuse-on-hyper-v/
Or ask SUSE Support Team write me by e-mail for detail
P.P.P.P.S.
In
./linux-3.10-rc2/drivers/scsi/storvsc_drv.c
I am not found sub-string "Fiber Channel"
As I undestand Linux Kernel roadmap/timeline traditions
need ask by backport needed patches to v3.10
To Microsoft Hyper-V for Linux Team:
Who must do it?
Again Hypev-V sysadmin[s] ?
P.P.P.P.P.S.
Sorry, if my msg not full "political correct"
I preffered solve problem as possibily earler, what wait big problems
Sorry, again . . .
