is there a mechanism for customizing VMM settings on a per-user

recently-created VM but, by default, new VM images are created in
/var/lib/libvirt/images, and that directory is not accessible to
non-root users.
as a non-root user, if i was about to start working with VMs, i'd
like to be able to invoke "virt-manager" and, *before* creating any
VMs, set some config options, such as where my images are going to go
(ideally, in a personal images directory). that would make those
images accessible to my account.
but if i fire up "virt-manager", i can see "Edit" ->
"Preferences"
but that doesn't allow me that kind of per-user configuration. does
that kind of configuration even exist? and, with those default
settings and permissions, how *would* one use libguestfs and guestfish
as a regular user?
or am i once again missing something critical?
There are two classes of libvirt driver connection
- Privileged, per-host connections
- Unprivileged, per-user connections
Xen provides a per-host connection. UserModeLinux and QEMU provide
both (qemu:///system and qemu:///session). VirtualBox just proivides
a per-user instance (vbox:///session) and so on.
Now by default in Fedora, when connecting to QEMU, virt-manager will
use the privileged per-host connection, so VMs end up in the system
directory /var/lib/libvirt/images.
Our goal (perhaps for F12) should be for local desktop virt use
cases to use the unprivileged QEMU connection qemu://session
by default, and have VM disk images stored in your home directory
