FYI the QEMU change merged in the following pull request changed to
return an EPERM errno for the thread affinity syscalls:

IOW, mesa's usage of this syscalls will still be blocked, but it will no
longer kill the process.

[Touch-packages] [Bug 1529079] Re: Can't start virtual machines with installed systemd-container package on Xenial

[Daniel Berrange]

> Not sure of the importance of that `Before` close there yet.

The Before/After properties provide the correct ordering of units on
shutdown. Without this dependency, there is no guarantee that libvirt-
guests.service will be invoked before systemd kills the machines, nor
that it will keep libvirtd.service running until the VMs have been
shutdown.

[Daniel Berrange]

> You can't specify an ordering dependency to an object that you create
*right now*, as there is no way to enforce them. So just dropping these
two lines ought to fix it.

You're only considering startup ordering. These properties also apply to
ordering when stopping units, and so these do make sense & are required
to get correct shutdown ordering for machines.
