I can't thank you enough Dario for starting this,
I have waited for this quite a while and never found the time for it
myself :-/
Hi!
Yeah, it was sitting in my TODO list for a little while as well.
Then I decided to mention that I'd do it in my talk at KVM Forum...
Which is usually a pretty good push for actually do it! ;-P
Looking at my todo notes I wondered if while touching it we should
right away also
add host-phys-bits-limit in the same spot?
See https://git.qemu.org/?p=qemu.git;a=commit;h=258fe08bd341d
Yes, I'm aware of it, and it looks easy to support.
And I agree that we can do it contextually.
I even have it in drafted patches, but I decided to fire these out as
early as possible, to capture some early feedback.
Thanks and Regards
