[Qemu-devel] [PATCH 0/2] vhost-user-scsi: add message for device reset

Posted by David Vrabel 7 years, 7 months ago

When a virtio scsi device is reset by a guest, the reset is not passed
on to the vhost-user backend. This reset may be necessary if a device
driver is restarted or the device is handed off between (for example)
SeaBIOS and the OS.

Iff the vhost-user-scsi backend reports that it supports a new "reset
device" feature, QEMU will send a VHOST_USER_RESET_DEVICE message when
the guest resets the virtio device.

Existing backends are unaffected.
