I don't thinks there's any generic resource about this issues, your best bet is to google for them, this is for example the patch related to that hw errata: http://lists.xen.org/archives/html/xen-devel/2013-01/msg01016.html It contains a link to the Intel SDM that has more info about the erratas. > And one more question, am I right that PV-guests are no more supported > in FreeBSD?
