Asias He dfd5d5692c tcm_vhost: Initialize vq->last_used_idx when set endpoint ... This patch fixes guest hang when booting seabios and guest. [ 0.576238] scsi0 : Virtio SCSI HBA [ 0.616754] virtio_scsi virtio1: request:id 0 is not a head! vq->last_used_idx is initialized only when /dev/vhost-scsi is opened or closed. vhost_scsi_open -> vhost_dev_init() -> vhost_vq_reset() vhost_scsi_release() -> vhost_dev_cleanup -> vhost_vq_reset() So, when guest talks to tcm_vhost after seabios does, vq->last_used_idx still contains the old valule for seabios. This confuses guest. Fix this by calling vhost_init_used() to init vq->last_used_idx when we set endpoint. Signed-off-by: Asias He <asias@redhat.com> Acked-by: Michael S.
