[Qemu-devel] Facing problems in running QEMU guest agents in Windows 2008 guest machine.

Hi,

I have a CenOS host machine running KVM and a Windows 2008 guest machine. I
am able to run "qemu-monitor-command" but not "qemu-agent-command".


[root@sdsr720-14 Windows_ISO]# virsh qemu-monitor-command --hmp vm_win_05
'info network'
Devices not on any VLAN:
  hostnet0: fd=23 peer=net0
  net0: model=virtio-net-pci,macaddr=52:54:00:7f:4a:5b peer=hostnet0

[root@sdsr720-14 Windows_ISO]# virsh qemu-agent-command vm_win_05
'{"execute":"guest-ping"}'

[root@sdsr720-14 Windows_ISO]#


[QEMU guest installation]
To install QEMU guest agent, I followed steps mentioned at following URL
http://wiki.qemu.org/Features/QAPI/GuestAgent#Example_usage


[Problem-1]
"qemu-ga.exe -s install" runs silently, "net start qemu-ga" gave error.

Following is the snippet from Windows shell.

    PS C:\puneet> .\qemu-ga.exe -s install

    PS C:\puneet> net start qemu-ga
    The service name is invalid.

    More help is available by typing NET HELPMSG 2185.

    PS C:\puneet>[root@sdsr720-14 Windows_ISO]#


[Problem-2]
When I double click the "qemu-ga.exe", it gives the following error.

"The application was unable to start correctly (0xc000007b). Click Ok to
close the application."

I tried some other possible ways also but could not get them working.


Regards,
~Puneet

The libvirt list is not quite the right mailing list for your
question. This list is for discussion about libvirt
development. Better ask at the qemu *user* list when you have problems
with the qemu guest agent.

BTW, 0xc000007b means STATUS_INVALID_IMAGE_FORMAT, which indicates
that either your file is not a valid PE executable or that it's a 32
bit app and tried to load a 64 bit DLL, but that's just a wild guess.

You could use Dependency Walker to track this down.
