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.

[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."

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. Claudio
