This error is ultimately coming from the QEMU guest agent inside
your guest. It spawns "hwclock" and this is failing for some reason.
You'll probably need to debug this inside the guest - strace the
QEMU guest agent, see where it fails, and then file a bug against
the distro for it.

This doesn't run hwclock as its merely reading the current time,.

I don't think you're doing anything wrong. This just looks like a guest
OS bug to me.
