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.
