[ovirt-users] What's going on open channel devices when migrating the Guest ?

[Jean-Pierre Ribeauville]

Hi,

I'm using a channel device between host and guest to exchange datas every 20 seconds.

On the Guest size , there is an open /dev/virtio file on which we read continuously what's
sent by the host.

My question is the following :
When migrating the Guest to another host ,  and the migrating back to the first one ,
the Guest software doesn't receive anymore datas from the host unless I restart the Guest software to re-open the /dev/virtio file.

Is there any way to detect in the Guest that migration has been done so we have to reopen  the file ?

Any hint is welcome .

Thanks for help.
