I can confirm this works, but it's a shame it doesn't work on autostart.
ACK if you clarify the error.

The autostart changes require getting a connection to the secret
driver which I felt may take more time than I had to figure out
how to get to work properly...
In any case, I adjusted the message as follows (same in 5/5):

I noticed that the nwfilter already unconditionally calls virConnectOpen("qemu://system"); so we're already in fact suffering from the problem with
autostart having a qemu dependency.
Given this, I'd support a patch which simply did
conn = virConnectOpen(privilege ? "qemu:///system" : "qemu:///session");
in storageDriverAutostart, provided that we ignore any errors from
virConnectOpen, and fallback to use NULL for the connection in that
case.
Obviously this is something we'll still need to fix properly in a
future release, but at least it'll make autostart of storage pools
with auth work in the common case in the short term for this release.
Both secret and qemu drivers are registered after the storage driver on
libvirtd startup, so autostarting these pools will only work on storage driver
reload. On libvirtd startup it fails with:
qemuConnectOpen:1033 : internal error qemu state driver is not active
oh, that's bad, fortunately we are just entering the freezing. nwfilter is
also loaded before qemu driver too, but it only creates the connection when
reloading. changing to load the storage and secret modules after qemu
module should be okay, unless there are other depedancies between those
modules in the middle.
(And it seems nwfilter only opens the qemu:// connection on reload)
conn = virConnectOpen("qemu:///system");
