Hi, everyone! We google a lot, but can''t find how to config the pvscsi on our ubuntu13.04 PV on HVM.There are some links http://wiki.xen.org/wiki/Paravirtualized_SCSI http://wiki.xen.org/wiki/Xen_Configuration_File_Options And we use the config option above Configure PVSCSI devices vscsi = [ ''/dev/sdc, 0:0:0:0'' ] I pass sdc to the hvm, but in our pvhvm (ubuntu13.04)

From: Jeremy Fitzhardinge <jeremy.fitzhardinge at citrix.com> Hi all, This series does two major things: 1. It converts the bulk of the implementation to C, and makes the "small ticket" and "large ticket" code common. Only the actual size-dependent asm instructions are specific to the ticket size. The resulting generated asm is very similar to the current
