Subject: [Qemu-devel] [PATCH 0/2] vhost-user-scsi: add message for device reset
Date: Mon, 19 Mar 2018 15:13:25 +0000 [thread overview]
Message-ID: <20180319151327.17989-1-david.vrabel@nutanix.com> (raw)
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.
David
