[Xen-users] ubuntu13.04 host and ubuntu13.04 guest how to config the pvscsi

[é æ <altman87120@xxxxxxxxx>]

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) there are no scsi device found, and no scsifront found.

And this is the sdc in the host.

This is the messages in our vm.

Does anyone can tell me why there is no scsifront and no use the  vscsi=['/dev/sdc, 0:0:0:0'] in our configuration ?
