Hi all,

Few months ago, Linaro has published the version 2 of the VM
specification [1].

For those who don't know, the specification provides guidelines to
guarantee a compliant OS images could run on various hypervisor (e.g
Xen, KVM).

Looking at the specification, it will require Xen to expose new
devices to the guest: pl011, rtc, persistent flash (for UEFI

The RTC and persistent will only be used by the UEFI firwmare.

Why would a guest booting without UEFI not want to use the RTC directly?

Sorry, I had only the VM spec in mind. Of course, an RTC could be used for guest booting without UEFI.
