Based on some digital archaeology performed by jtomko, it's been determined
that the persistentAddrs variable is no longer necessary...
The variable was added by:
commit 141dea6bc7222107c2357acb68066baea5b26df3

Add persistence of PCI addresses to QEMU
Where it was set to 0 on domain startup if qemu did not support the
QEMUD_CMD_FLAG_DEVICE capability, to clear the addresses at shutdown,
because QEMU might make up different ones next time.
As of commit f5dd58a6088cfc6e8bd354b693d399807a8ec395

qemu: Extended qemuDomainAssignAddresses to be callable from
everywhere.
this was broken, when the persistentAddrs = 0 assignment was moved
inside qemuDomainAssignPCIAddresses and while it pretends to check
for !QEMU_CAPS_DEVICE, its parent qemuDomainAssignAddresses is only
called if QEMU_CAPS_DEVICE is present.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
