Public bug reported:
I have configured host filesystem access via virt-manager.
<filesystem type='mount' accessmode='squash'>
<source dir='/tmp/share1'/>
<target dir='/hostshare1'/>
<alias name='fs0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x09'
function='0x0'/>
</filesystem>
<filesystem type='mount' accessmode='mapped'>
<source dir='/tmp/share2'/>
<target dir='hostshare2'/>
<alias name='fs1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x0a'
function='0x0'/>
</filesystem>
now, in the guest, I can mount /hostshare1 -t 9p -o
trans=virtio,version9p2000.L,access=any,posixacl /mnt/
but I cannot list the directory. I get a permission denied error.
cat /etc/apparmor.d/libvirt/libvirt-039f126b-
da58-4dba-9317-4c7586c34a61.files

but I needed to
sudo aa-complain libvirt/libvirt-039f126b-da58-4dba-9317-4c7586c34a61
in order to be able to list the directory. I cannot read or write files,
though.
I expected it to work fine.
