[Qemu-devel] How to test vm channel with windows guest

Hello,

We have established a communication channel between a ubuntu 10.04 host and a windows xp guest using vm channel.  

At the host end we have used a unix socket. Below is the libvirt related config

===========================================================
<channel type='unix'>
  <source mode='bind' path='/tmp/guestfs' />
  <target type='virtio' name='org.windows-kvm.port.1'/>
 <address type='virtio-serial' controller='0' bus='0'/>
</channel>
===========================================================

To test if the channel has been successfully created or not we run the "vioser_test" at the guest and. At the host end we run "socat /tmp/guestfs -".

We find that while the guest is able to send commands to the host, it does not work from the host to the guest end. 

Is the source code for vioser_test available for reference. Also is there any reference documents to write agents like vioser_test utility.

Thanks in advance.

I'm not familiar with this vioser_test utility, is it part of the virtio 
driver package for windows? If so the source code is available here:

http://git.kernel.org/?p=virt/kvm/kvm-guest-drivers-windows.git

Amit's virtio-serial test suite is also available for reference:

I'm not sure how applicable it is for windows though.

Hello Michael,
Thank you very much for pointing to the virtio driver package for windows. It does have the vioser-test utility.
