			This is followup patch to the one submitted back in Oct, 19 https://lists.gnu.org/archive/html/qemu-devel/2019-10/msg02102.html My mistake here, I took my eyes of the mailing list after I got the initial thumbs up. This patch follows up on Markus comments in the above link. Purpose of this patch: We want to print guest name for errors, warnings and info messages. This was the first of two patches the second being MCE errors targeting a VM with guest name prepended. But in a large fleet we see many other errors that disable a VM or crash it. In a large fleet and centralized logging having the guest name enables identify of owner and customer.
