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 at 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 at sdsr720-14 Windows_ISO]# virsh qemu-agent-command vm_win_05

[root at sdsr720-14 Windows_ISO]#

[QEMU guest installation]
To install QEMU guest agent, I followed steps mentioned at following URL

"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 at sdsr720-14 Windows_ISO]#

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.
