    vhost-user-scsi: Introduce vhost-user-scsi host device · f12c1ebd
    Felipe Franciosi 提交于
    This commit introduces a vhost-user device for SCSI. This is based
    on the existing vhost-scsi implementation, but done over vhost-user
    instead. It also uses a chardev to connect to the backend. Unlike
    vhost-scsi (today), VMs using vhost-user-scsi can be live migrated.
    
    To use it, start Qemu with a command line equivalent to:
    
    qemu-system-x86_64 \
           -chardev socket,id=vus0,path=/tmp/vus.sock \
           -device vhost-user-scsi-pci,chardev=vus0,bus=pci.0,addr=...
    
    A separate commit presents a sample application linked with libiscsi to
    provide a backend for vhost-user-scsi.
