Hi all,

I want to get the statistics of block device of HVM. I found xen createda vbd (/sys/bus/xen-backend/devices/vbd-1-768) when I created a HVM. Butthe 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. SoI'm wondering vbd is not really used by HVM. Could anyone kindly tell mewhich device is used for block device in dom0 for HVM? Thanks in advance.

Randy
