Yes, I'm aware of this issue, unfortunately the way to solve it it's not

In order to do a proper power off when running as Dom0 we would have to
modify ACPICA code, which is a separate upstream project that's used by
a bunch of different OSes. Linux does it this way, but then they have to
keep all this local modifications on top of upstream ACPICA, which
increases the maintainership burden.

Do you mean that CentOS 7 guests do not poweroff properly? Are those PV
or HVM guests?

I usually use Debian guests when I have to test Linux and have never
experienced this.

Yes, I've also experienced this once or twice. The problem is that the
blkback error path can get deadlocked depending on the situation. I have
to look into cleaning it when I have some time.

Thanks for the testing and the list of issues!
