Just one thing: to boot kernel correctly I must specify pci=nommconf At least it's better than all-generic-ide pci=nommconf irqpoll which i had to specifiy with ICH9 chipset to boot non xen 2.6.18 kernels, and still it it did not work with xen vanilla kernel 2.6.18, the only xen enabled kernel which reasonably worked with ICH9 chipset was from ubuntu.Another question, as i understand with VT-d and pci passthrough enabled in the xen-3.2 kernel it should be possible to give HVM domU direct & priviliged access to the whole pci disk controller. But is it possible to give HVM domU direct & priviliged access only to specific hard disk attached to this disk controller? Thanks Alex as kernel command line argument.Thanks Alex-- WBR, i.m.chubin _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
