solaris domU hvm pv disk io support
By edp on Aug 25, 2009
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.
