[Qemu-discuss] virtio channel device usage

[Jean-Pierre Ribeauville]

Hi,

 

I set up a channel device between host and Windows guest by adding such lines :

 

<channel type='unix'>

      <source mode='bind' path='//var/lib/libvirt/qemu/omnivision_123.agent'/>

      <target type='virtio' name='omnivision_123.agent' />

      <address type='virtio-serial' controller='0' bus='0' port='2'/>

    </channel>

 

 

 

I notice that , if the host side has not open the socket, then write issued by the guest fails with following error :

 

C:\>copy omv_bdc_var   "\\.\Global\omnivision_123.agent"

Used to indicate that an operation cannot continue without blocking for I/O.

        0 file(s) copied.

 

Is it the waited behavior ?

 

 

Thanks for help.

 

Regards,

 

J.P. Ribeauville
