Hi, I was wondering if I'm alone with this: the vhost-switch example crashes on client disconnects if the client send a RESET_OWNER message. That's at least the case for QEMU and vhost-user mode (I suppose vhost-cuse is legacy now). And it really ruins the party when playing with this because every VM shutdown or guest reboot triggers.
I was looking deeper in the librte_vhost, and I found that reset_owner() is doing cleanup_device and then init_device - but without letting the user know. So vhost-switch crashed in its main loop over continuing to use the device, namely calling rte_vhost_dequeue_burst (with dev->virtqueue[]->avail == NULL). Do we simply need another hook in the vhost API, similar to the destruction notification? Jan -- Siemens AG, Corporate Technology, CT RTC ITP SES-DE Corporate Competence Center Embedded Linux
