And in this week, I tried your Windows Guest Agent patches. It is a
little hard way.
At the first I wrote my work.
0. my node OS is RHEL 6.1.
1. build some mingw packages (mingw32-gcc, mingw-32-glib2...)
2. apply your patches to qemu-kvm HEAD source. There is no error.
3. boot WinXP SP3 and Win Server 2008 R2 with VirtIO Console and
Guest Agent options.
4. install VirtIO Serial driver for Windows in
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/virtio-win-0.1-15.iso
5. communicate to node OS with viosel-test.exe included upper iso file is OK
6. copy qemu-ga.exe with some dlls included in mingw32 packages
7. 'qemu-ga --service install' does not work well. but 'qemu-ga -s
install' works well.
I see the problem, small bug in the getopt_long() usage that wasn't
triggering on POSIX. I'll fix that up shortly.
8. qemu-ga.exe works. And get good response for guest-info command.
9. But after 30 seconds, qemu-ga.exe displays following and not work
correctly.
1328840605.265625: critical: error retrieving overlapped result: 995
1328840605.296875: critical: channel error, removing source
If possible, could you point my work?
Can you reproduce with the -v option added and post the the output? I
haven't encountered this error code and the documentation for it seems
strange. Does this occur with both WinXP and 2008?
Yes, it occurs with both WinXP and 2008.
And pastes the log with '-v'
C:\qemu-ga>qemuga.exe -v

If it's not too much trouble, can you try to reproduce with qemu.git
(for WinXP SP3)? Wondering if qemu vs. qemu-kvm is affecting the
virtio-serial driver.
Yes. I am using the qemu.git from
http://repo.or.cz/w/qemu.git.
In addition, now I change the hypervisor from RHEL 6.1 default to
qemu git tree. But same problem occurs.
Strange, I can't seem to get the virtio-win-0.1-15.iso vioser drivers
working with either qemu.git or qemu-kvm.git. I thought I was using them
for XP SP3, but apparently I had switched over to using RHEL6ga drivers
at some point (virtio-win-1.1.16.iso), which I believe are older than the
Fedora ones you're using.
However, there was an issue with the RHEL6ga drivers where an
ERROR_SYSTEM_NO_RESOURCES was sometimes being reported in place of what
where I'd normally expect an EOF with the linux drivers. So my guess is
that has since been changed to report ERROR_OPERATION_ABORTED instead, so
please also apply the following patches and see if these fix the issues
you're having:
1) qemu-ga: fix incorrect getopt_long() usage
https://github.com/mdroth/qemu/commit/b5f4349763936007e1a33ba99d9ffb6b75a49b36
2) qemu-ga: win32, treat ERROR_OPERATION_ABORTED as EOF
https://github.com/mdroth/qemu/commit/7418bbf903e639ec22c394771f5ff03f18bd1275
Thanks
