What version of the virtio-win drivers are you using? More specifically,
what's the name of the ISO/package you used? I'm not sure how
"Driver Date" maps to actual virto-win releases.

There is a test utility on the virtio-win ISO called "vioser-test.exe".
I'd recommend running that to confirm whether or not it's a qemu-ga
issue. Before you run it, attach something to the host-side socket to
confirm you get the expected output from the test utility, such as
`nc -U /tmp/qemu-ga.w2008.0.sock`

Also, any logs/output from the QEMU process may provide some
clues as well.

This implies the driver isn't installed/working properly and the virtio-serial
device isn't present.

Vadim: any suggestions for debugging?

A linux guest with qemu-ga installed? If that scenario isn't working for you
it's a different issue, but I'd be interested in the output you see when
running qemu-ga in the linux guest as `./qemu-ga -v` (as root) and then sending
the guest-ping command.

Actually I think what's happening here is socat is getting an EOF from
your echo process and closing the stream before qemu-ga has a chance to
respond. Retry with:

echo "{'execute':'guest-ping'}" | socat stdio,ignoreeof unix-connect:/tmp/qemu-ga.w2008.0

Re: [Qemu-devel] Fw: Qemu-ga : Guest Agent : Win 2008-64bit not working

[Pengfei Hu]

I found the same problem occur at Win7. At vioserial\app\device.app:
BOOL CDevice::Init(BOOL ovrl)
{
    PWCHAR DevicePath = NULL;
    if ((DevicePath = GetDevicePath((LPGUID)&GUID_VIOSERIAL_PORT)) != NULL)
    {
        m_hDevice = CreateFile(DevicePath,
                             GENERIC_WRITE | GENERIC_READ,
                             0,
                             NULL,
                             OPEN_EXISTING,
                             ovrl ? FILE_FLAG_OVERLAPPED : 
FILE_ATTRIBUTE_NORMAL,
                             NULL );

        if (m_hDevice != INVALID_HANDLE_VALUE)
        {
            printf("Open vioserial device  %S.\n", DevicePath);
            return TRUE;
        }

    }
    DWORD err = GetLastError();
    printf("Cannot find vioserial device. %S , error = %d\n", DevicePath, 
err );
    return FALSE;
}

GetLastError return 5. This mean not enough privilege. Running with 
administrator will solve this problem. Or you may run "qemu-ga -s install" to 
install as a service.

The issue was resolved after running the qemu-ga in dos window with Administrator privileges.
