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. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
