Hi, Blktap devices information isn''t shown by xentop currently. xen-unstable c/s 17813 said "blktap devices have statistics counters (e.g., rd_req, wr_req, oo_req) prepended by tap_". In fact, it is as follows. # ls -l /sys/devices/xen-backend/tap-1-769/statistics/ total 0 -r--r--r-- 1 root root 4096 Dec 3 20:37 oo_req -r--r--r-- 1 root root 4096 Dec 3 20:37 rd_req -r--r--r-- 1 root root 4096 Dec 3 20:37 rd_sect -r--r--r-- 1 root root 4096 Dec 3 20:37 wr_req -r--r--r-- 1 root root 4096 Dec 3 20:37 wr_sect The statistics counters haven''t had "tap_" because it was removed by linux-2.6.18-xen c/s 34. This patch reverts xen-unstable c/s 17813, then we can get the blktap devices information by using xentop.
