Hi,
I tried the patch v2,with the following config.
Guest os : win7 32bit professional
Host os : fedora 17
Command:
qemu-kvm -enable-kvm -name win7 -M pc-0.15 -m 1024 -smp 2 -boot c -device
virtio-serial -drive
file=/home/libaiqing/vss/win7.img,if=virtio,index=0,format=qcow2 - -monitor
stdio -vga qxl -vnc :1 -chardev
socket,id=charchannel0,path=/var/lib/libvirt/qemu/wahaha1_requester,server,nowait
-device
virtserialport,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.1
Issue:
1 Extcuting the command "net start qemu-ga" failed,but the command
"qemu-qa.exe -m virtio-serial -p \\.\Global\org.qemu.guest_agent.1" is ok.
2 executing the command "{"execute":"guest-fsfreeze-freeze"}" failed,the
output is:
[root@fedora121 ~]# socat stdio,ignoreeof
unix-connect:/var/lib/libvirt/qemu/wahaha1_requester
{'execute':'guest-info'}

Could you give me some advise to debug this problem ? I can provide more
information if need.

Subject: [Qemu-devel] [RFC PATCH v2 00/11] qemu-ga: fsfreeze on Windows using
VSS
Hi,
This patch series is attempts to add fsfreeze support for Windows
qemu-guest-agent.
changes from v1:
- Fix out-tree build by stop using recursive Makefile
- Added script to extract VSS SDK headers on POSIX systems using msitools
(thanks Paolo)
- Remove some unnecessary header files
v1: http://lists.gnu.org/archive/html/qemu-devel/2013-02/msg01963.html
* Description
In Windows, VSS (Volume Shadow Copy Service) provides a facility to
quiesce filesystems and applications before disk snapshots are taken.
This patch series implements "fsfreeze" command of qemu-ga using VSS.
* How to build & run qemu-ga with VSS support
- Download Microsoft VSS SDK from:
http://www.microsoft.com/en-us/download/details.aspx?id=23490
- Setup the SDK
scripts/extract-vsssdk-headers setup.exe (on POSIX-systems)
- Specify installed SDK directory to configure option as:
./configure -with-vss-sdk="path/to/VSS SDK" --cross-prefix=i686-w64-mingw32-
- Make qemu-ga.exe
- Install qemu-ga.exe and qga/vss-win32-provider/qga-provider.{dll,tlb} into
the same directory in guests
- Run `qemu-ga.exe -s install' and `net start qemu-ga' in the guests
Any feedback are appliciated.
