I can attach a block device
$ sudo xm block-attach 27 file:/local/xen/lindi-exp1/disk.img /dev/xvda w
$ sudo xm block-list 27
Vdev BE handle state evt-ch ring-ref BE-path

[ 81.988522] blkfront: xvda: barriers enabled
[ 81.988852] xvda: xvda1
[ 81.988969] xvda: p1 size 979902 exceeds device capacity, limited to end of disk
and also detach it:
$ sudo xm block-detach 27 51712
