Quoting Jaap Winius <jwinius at umrk.nl>:

... the same problem causes the libvirt-qemu issue, but I was only
able to fix it on one of the two affected Debian stretch systems by
adding similar content to the same file:

local config file for the libs test

---

whitelist: /usr/bin/qemu-system-x86_64: - '^/\[aio\]$'

I can now report that this also worked on the other Debian stretch
system after it was reboot.

Still no idea on how I would go about doing this on a Debian wheezy system.

Cheers,

Jaap
