Public bug reported:
Based on 1815452, specifically the PPA from in Comment #17.
First, trying gives me these apparmor denied entries (complete log in
default_PPA_denies.log):

Worked around them (or so I think) by adding to local/abstractions/libvirt-qemu:
/proc/modules r,
/proc/driver/nvidia/ r,
/proc/driver/nvidia/** r,
/usr/share/egl/ r,
/usr/share/egl/** r,
/sys/devices/** r,
/sys/devices/ r,
/dev/nvidiactl rw,
This doesn't give anymore AppArmor denials, but does result in (full log in
my_attempted_workaround.log):
Feb 27 09:40:16 desktop libvirtd[1468]: Unable to read from monitor: Connection

Feb 27 09:40:16 desktop libvirtd[1468]: internal error: qemu unexpectedly
closed the monitor: qemu-system-x86_64:
../src/gallium/drivers/llvmpipe/lp_texture.c:499: llvmpipe_resource_get_handle:
Assertion `lpr->dt' failed.
Other relevant bits:
I'm using the nvidia 415 driver from the graphics-driver ppa.
