Sorry, i wrong to write, is 4.0.1-rc1, i have always take from xen-4.0-testing.hg last weeks about xen 4 Yesterday i have try tap2:aio in cfg files and work, is blktap how not work with lenny, pv_ops kernel and xen 3.4.3 or 4.0 With tap2:aio minor ram used by dom0 but i see minor performance on domU (mainly on start) All important fix do in unstable are merged with xen-4.0-testing.hg?
