util/qemu-error: prepend guest name to error message to identify affected VM owner
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.
