Hi all,

I want to get the statistics of block device of HVM. I found xen created a
vbd (/sys/bus/xen-backend/devices/vbd-1-768) when I created a HVM. But the
vbd statistics (e.g. rd_req, wr_req, wr_sect, rd_sect) are all 0. For PV
guest or PV driver, I can get the vbd's statistics directly. So I'm
wondering vbd is not really used by HVM. Could anyone kindly tell me which
device is used for block device in dom0 for HVM? Thanks in advance.
If the HVM domU uses PV drivers (like gplpv) the stats will be updated.

Yes, but I want the stats without pv drivers.
