Just to be clear: In this case "support for old PV guests" really means, "Support for running new versions of Linux in PV mode on old (non-HVMLite-capable) hypervisors". And yes, that is the plan: in 5 years' time, if you're still running Xen 4.6, to run a Linux 5.17* guest you'll have to run it in HVM mode, and you won't be able to use it as a dom0. (Xen 6.1 will still support Linux 4.5 running in PV mode, however.) -George * Making up version numbers here, obviously
