Debian stable issue #2: <pm> causes Error "setting ACPI S3 not supported"

My version numbers are the same as Whonix ™ for KVM (click expand and scroll down to check version numbers).

Leaving

  <pm>
    <suspend-to-mem enabled='no'/>
    <suspend-to-disk enabled='no'/>
  </pm>

will result in this error

Error starting domain: unsupported configuration: setting ACPI S3 not supported

Removing the … block solves that issue.

But there are 2 more debian stable related issues, that I will post in separate threads. So maybe we don’t have to make this change, but can fix the root of this issue.
