That value is exposed by blkback, and among other stat counters, it''s a signed integer: drivers/block/xen-blkback/common.h struct xen_blkif { ... int st_rd_req; int st_wr_req; int st_oo_req; int st_f_req; int st_ds_req; int st_rd_sect; int st_wr_sect; I don''t think these values should be negative ever, but when they overflow (which happens eventually), they do, and this leads to bad conversion in xentop. I think the best solution would be to change the above m...
