Great!  What kind of client are you writing?

Yes, it should be safe.  Indeed, SD_OP_DEL_VDI should be in
include/sheepdog_proto.h because we need to support deleting snapshots
from qemu-img commands in future.

See vdi_delete() in collie/collie.c.  It would tell you how to use a
SD_OP_DEL_VDI operation.
