solaris domU hvm pv disk io support

recently i finished up working on pv disk io support for hvm solaris domains when running under the xvm hypervisor. after finishing this work i gave a presentation on it to the solaris sustaining organization. i figured that my slides might be of interest to other folks who want to know how hvm pv disk io work on solaris, so i'm posting my presentation here.

solaris hvm pv disk io support is noticeably different from linux hvm pv disk io support. specifically, when running solaris in an hvm domain with pv disk access enabled, the pv disk paths don't change. ie, the disks in an hvm domU that is using pv io still look like ide disks, although internally requests to these ide disks get routed to dom0 via paravirtualized disk device drivers. the magic is all done via driver replacement and layering. see my presentationfor all the gory details.
