From: Max Goodhart <git...@chromakode.com> This fixes a blank screen when viewing a VM with virtio graphics and gl-accelerated Spice display on Ubuntu 22.04 / libvirt 8.0.0 / qemu 6.2.
Without these AppArmor permissions, the libvirt error log contains repetitions of: qemu_spice_gl_scanout_texture: failed to get fd for texture This appears to be similar to this GNOME Boxes issue: https://gitlab.gnome.org/GNOME/gnome-boxes/-/issues/586 Signed-off-by: Max Goodhart <c...@chromakode.com> --- src/security/virt-aa-helper.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/security/virt-aa-helper.c b/src/security/virt-aa-helper.c index 1f1cce8b3d..b314d2a059 100644 --- a/src/security/virt-aa-helper.c +++ b/src/security/virt-aa-helper.c @@ -1316,7 +1316,7 @@ get_files(vahControl * ctl) virBufferAddLit(&buf, " \"/dev/nvidiactl\" rw,\n"); virBufferAddLit(&buf, " # Probe DRI device attributes\n"); virBufferAddLit(&buf, " \"/dev/dri/\" r,\n"); - virBufferAddLit(&buf, " \"/sys/devices/**/{uevent,vendor,device,subsystem_vendor,subsystem_device}\" r,\n"); + virBufferAddLit(&buf, " \"/sys/devices/**/{uevent,vendor,device,subsystem_vendor,subsystem_device,config,revision}\" r,\n"); virBufferAddLit(&buf, " # dri libs will trigger that, but t is not requited and DAC would deny it anyway\n"); virBufferAddLit(&buf, " deny \"/var/lib/libvirt/.cache/\" w,\n"); } -- 2.34.1
