I did something wrong or there is a bug or unexpected case?
Thanks for any reply.
Not seen anything like that before. I can only assume it's to
do with
language support. It seems like msbuild is emitting characters
that the
shell is
not handling correctly. I suspect you'll be ok if you use an
English
character
set but I'll try to figure out what the script is/isn't doing.
Paul
I installed english language pack and solves the problem.
Ok. So we know what the problem was. We need to figure out a
solution
to
that.
Thanks, for now I built with english windows.
After gave me other error about no sufficent permission on one
exe of
WDK, I tried to execute as administrator and did max permissions
to
everyone on the file but not, I solved also that adding nosdv.
I've seen problems running sdv where some of the processes it
kicks off
seem to conflict on one of the log files, so it bails with a lack
of write
permission. Is that the sort of thing you saw?
Probably, you need that I retry and post the exactly output of error?
After I had near the end another error where I not found a
workaround:

That looks like git is not on your path. The build script adds an
archive of
the
source to the output. I should probably just remove that from the
script.
I saw that in repository folder\xenbus\(x64|x86) seems there are
the
drivers ready, is correct and can be tried?
Yes. They should be good to go.
Installed all 5 drivers in windows 7 pro 64 bit sp1.
On boot now take very long time (much more time that with other
windows
pv or without any) until arrive at login screen, network card is not
visible (show unable to boot both emulated and pv network card).
Testsigning is enabled and the other pv drivers was removed and
rebooted
before install this new.
On same dom0 and domU with other pv drivers (of James Harper) I
had
only
these 2 problems:
- occasional network disappaer after some hours or days (probable
xennet
crash)
- 2-3 time of "hang" after restore with qxl vga and vdagent enable
This is the domU's cfg:
name='W7-02'
builder="hvm"
memory=2048
vcpus=2
vif=['bridge=xenbr0,mac=00:16:3e:42:a2:5f']
disk=['/mnt/vm/disks/W7-
02.disk1.xm,raw,hda,rw',',raw,hdb,ro,cdrom']
boot='dc'
device_model_version="qemu-xen"
viridian=1
vnc=0
keymap="it"
on_crash="destroy"
vga="qxl"
spice=1
spicehost='0.0.0.0'
spiceport=6003
spicedisable_ticketing=1
spicevdagent=1
spice_clipboard_sharing=0
spiceusbredirection=4
soundhw="hda"
localtime=1

I tried also disabling qxl, vdagent, audio and usb:
name='W7-02'
builder="hvm"
memory=2048
vcpus=2
vif=['bridge=xenbr0,mac=00:16:3e:42:a2:5f']
disk=['/mnt/vm/disks/W7-

spiceport=6003
spicedisable_ticketing=1
spicevdagent=0
spice_clipboard_sharing=0
#spiceusbredirection=4
#soundhw="hda"
localtime=1
#usbversion=2
But I had same problems.
Dom0 is wheezy with xen-unstable of some days ago plus some libxl
patch
(https://github.com/Fantu/Xen/tree/rebase/m2r-staging) and qemu
2.1.1
Now I'll try also with W8.
If you need more details and/or tests tell me and I'll post them.
If you could enable xen_platform_log in QEMU then the QEMU log
should
tell us what's going on. If you don't know how to do that then the
way I do it
is to create a file called 'events' under /tmp populated with the
single line:
xen_platform_log
and then I add:
device_model_args=[ "-trace", "events=/tmp/events"]
to my config. QEMU by default is built to send traces to stderr, so
you
should see the log entries appear in /var/log/xen/qemu-dm-<vm
name>.log.
Did you try installing the drivers in a fresh VM? It's possible
that there is still
some remnant of the GPLPV drivers around - uninstalling drivers on
Windows
is tricky.
Thanks for reply.
Tried with trace (log in attachment), with a fast look a saw a strange
mac different from the one setted in cfg.
I tried removing fixed mac in xl cfg but the network card problem
persist.
The old pv should be completly removed, I used also the bat for remove
the registry keys and file, not only the unstall from control panel.
I'll try also a clean install ASAP.
Your PV storage looks fine, but the problem with your network is here:

What this means is that your frontend waited for a very very long
time for your backend to go connected, and it failed to do so. It
then give up and you get the above cascade of error logging. I
suspect the problem is a lack of the following netback fix:
commit 279f438e36c0a70b23b86d2090aeec50155034a9
Author: Paul Durrant <Paul.Durrant@xxxxxxxxxx>

xen-netback: Don't destroy the netdev until the vif is shut down
Without this patch, if a frontend cycles through states Closing
and Closed (which Windows frontends need to do) then the netdev
will be destroyed and requires re-invocation of hotplug scripts
to restore state before the frontend can move to Connected. Thus
when udev is not in use the backend gets stuck in InitWait.
With this patch, the netdev is left alone whilst the backend is
still online and is only de-registered and freed just prior to
destroying the vif (which is also nicely symmetrical with the
netdev allocation and registration being done during probe) so
no re-invocation of hotplug scripts is required.

I found it applied upstream:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-
next.git/commit/?id=279f438e36c0a70b23b86d2090aeec50155034a9
But not in 3.2-stable branch, I tried to apply it on latest Wheezy
(debian 7) kernel source but there are too many difference and I was
unable to apply it manually.
Can someone give me advices please?
Use kernel from wheezy-backports (3.14+59~bpo70+1) can be a good thing
and very reliable? I plain to use new versions also in production ASAP
(if I can solve theoccasional network crash on windows I have with
gplpv and hope to solve with these drivers), with the agent lite of
these drivers should finally solves also the post-restore problem of
time(and users unable to login) with the windows domUs in a domain.
Now I'll do a fast test with kernel for backports to solves if solves
the problem.
Thanks for any reply and sorry for my bad english.
I tried the kernel from backports and solves the network and very long
boot time problem.
The xen agent lite problem still persist instead, on my latest test on
windows 7 show xenlite service running but xl shutdown and update time
on restore are still not working :(
I not saw an agent error in windows events log but I saw this error:
the BIOS ACPI not contains a IRQ for the device in PCI slot 6 function 0
With hwinfo I saw that is realtek emulated network card, is it correctly
since pv driver is in use?
Can you send the qemu log again? If you are still seeing the realtek device in
the guest it suggests your PV frontend is still not installed correctly.
Log in attachment.
The windows device management still show realtek even if is not used
(show error 12 - resources conflict on it), xen pv network device
instead now is showed ok and is working.
I think there's a compatibility problem. What happens if you simply xenstore_write "halt"
into control/shutdown. (xl appears to write "poweroff" instead).
Here I not understand if is something I must try and post the result or
you already found the exacly problem.
Thanks for any reply.
