GPLPV drivers 0.9.12-pre9 upload

GPLPV drivers 0.9.12-pre9 upload

[James Harper]

I've just uploaded 0.9.12-pre9. Please read the following before using:

1. Windows 2000 is no longer included in the binary distribution. It
didn't work.

2. qemu network and disk adapters are disabled, but will now appear as
having failed due to a change in the hiding code. This is cosmetic
(you'll get a warning on start that a service or driver failed to start)
but the effect is the same, except you won't get strange things
happening as a result of pci devices just disappearing - I was seeing
delays in places during startup and shutdown.

3. If you are using the latest Xen 3.3.1 hg (maybe 3.3.0 too?), the
qemu_disable_patches.diff patch applied to the ioemu-remote git repo
(after 'make tools' has downloaded it, or after you've updated it to the
latest) will completely remove the ide disks and network interfaces,
leaving the cdroms as emulated by qemu. This is how things should be
going forward - qemu cdrom's means you get eject and virtual image swap
etc, and performance on a cdrom is hardly critical. Hopefully these
patches will make it into Xen 3.4.

4. Please test in a dev environment. I haven't broken my test servers
during upgrade or anything, but testing first is just common sense.

5. 64 bit block addressing is in place but not really tested. If you
have block devices >1TB that didn't work previously, please give it a go
and let me know.

6. Save+restore is working for me at the moment, please report any
issues.

Go to http://www.meadowcourt.org/downloads/ for the gplpv driver
download and, if you want, the qemu_disable_patches.diff patch.

See the thread in xen-devel with a subject of 'disable qemu PCI devices
in HVM domains' for an explanation of how the qemu device disabling
works.

I had a question on compiling the code few days ago. Could you answer that?

Did you want me to apply that .diff to the current qemu-xen-unstable ?
If so could you please post it to the list (with an appropriate
Signed-off-by section which should probably include the original
authorship trail ?

Or should I pick up Steven Smith's patch ?

Alternatively I'm happy to wait, but current unstable is what will
become 3.4 and if you're happy with the interface and the code I'm
happy to do so right away.

Ian.

My patch is just Steven Smith's patch anyway, with the fix to make it
apply to the current head and the addition of GPLPV as product number 2,
so go ahead and apply his patches please and then I'll submit the GPLPV
addition after that.

I've tested Steven's patches enough that I'm happy with them.

OT, I'm curious, why is Xen in hg but the qemu stuff in git?

Thanks

Doh. That website is on IIS, and will only let you access files with extensions it knows about.

I've attached the patch to this message.

to disable the device drivers, or boot into safe mode which will also

Upstream qemu uses git, so it's easiest to do the same. We'll probably do
the same for our Linux tree when we move from 2.6.18 to upstream pv_ops.

Xen itself uses mercurial just because that's what we switched to when
bitkeeper went away.

Dear James
My Windows 2003 32 with the latest drivers (0.9.12-pre9 ) has this error

Driver detected an internal error in its data structures for XenVbd

The following  boot-start or system-start driver(s) failed to load: XenVbd
Any idea

Forgot one important thing. /GPLPV isn't required anymore. Use /NOGPLPV
to disable the device drivers, or boot into safe mode which will also
disable them.

You press F8 just as the BIOS finishes. If you only have a single entry
in your boot.ini then Windows won't wait very long (or at all) to wait
for that keypress.

If you have trouble getting vnc up between starting the domain and
windows booting, try starting the domain paused (xm create -p), then
connect with vnc, then unpause the domain (xm unpause).

The reason for the 0x7B messages will be that xenhide.sys is attached as
an upperfilter to the ide devices (it's this sort of thing that is the
reason why I want to make qemu do the hiding!). after booting into safe
mode, use regedit and look for any upperfilter lines containing
'xenhide' and remove them, but only if you have otherwise removed the
drivers.

A few people have reported that in the past, but we were never able to
get to the bottom of it.

When you get that error after booting, are you actually running on the
PV drivers and not the qemu devices any more?

I'll ask over on the ntdev list what that message could mean.

[Venefax]

Dear James
I am unable to connect via VNC to my windows domain, since I executed this
command;

xend restart

since then the graphic virtual machine manager would not connect to the
local machine. I also did execute this command, to see if it would work, but
it did not:
service libvirtd restart

How do I my graphic virtual machine connect again? my Xen domains are
working fine, it seems. I use SLES SP2.
Yours
Federico

I installed the drivers into a existing Vista 32 bit HVM which had
older version of the drivers installed and it bsod on reboot with
0x0000007B, I tried /nogpl and also safe mode but neither worked, I
reinstalled Vista and tried again but I got the same result.

Once the qemu drivers have been disabled by booting with /gplpv (or
without /nogplpv in newer versions) is it sufficient to reset/reboot
the domain to boot without the drivers, or does it need to be
destroyed and created again for the qemu emulation to resume?

Fresh install of vista + 0.9.12 pre9 = 0x0000007B :(.

What do I need to do to debug this?

I am running 3.3.1 rc4, I can try 3.3  if you think it might help,
perhaps I need the patch for hiding devices?

I posted this earlier in the wrong thread, I tried to use the
qemu_disable_patches.diff today with 3.3.1 rc4 but it didn't hide the
devices or change cdrom to emulated when using the pre11 drivers, this
is what I did:

hg clone -r 3.3.1-rc4 http://xenbits.xensource.com/xen-3.3-testing.hg
cd xen-3.3-testing.hg
make tools # I believe this is necessary to pull ioemu-remote ?
cd tools/ioemu-remote
patch -p1 -i /usr/src/qemu-pci-disable.patch # I removed the last
chunk of the patch which changes vl.c as the changes are in 3.3.1-rc4.
make clean
cd ../../
make clean
make tools
make install-tools
/etc/init.d/xend restart

I did not recompile xen, only the tools.

In my vista hvm the Intel IDE and Realtek NIC are still visible, and
cdrom is XEN PV not ioemu/qemu.

Is my method incorrect?

It looks to be. Can you confirm that the qemu-dm installed by 'make
install-tools' is definitely the one being used by your domain?

One of the other changes is that logging should appear in the logfile
for that domain. Can you have a look there and see what's in there?

The method I used does not work, it appears that after patching and
recompiling the binary does not get updated, it is the same as the one
produced by the first "make tools".

Instead I started from scratch and immediately after "make tools"
downloaded ioemu-remote git I paused the process, applied the patch,
and then resumed, this time the binary is different, and in my vista
vm the devices have changed, but they are still not correct, both are
now emulated:

QEMU HARDDISK ATA Device
QEMU QEMU DVD-ROM ATA Device
Realtek RTL8139C
