I wasn't awake this morning it seems (or did to omuch at once), so I beg
your pardon and resummarize.
Also I had the chance to try the fs forwarding on a zestyl level
libvirt/qemu and it worked fine.
- The /srv/video rule obviously is just the case reported for a share that
exports this source.
Ok, so we need three things:
1. the zfs rules to be generated which is bug 1677398
2. for this one here understand the video rule if/how it is releated and
generate it accordingly
3. check where/why qemu does these fowner/fsetid things and create a rule for
it depending on that.
If it does so
It seems, I have found the issue at least for my side. I noticed the
following message in the kernel log:
Sep 16 19:14:36 nostromo kernel: [ 8050.077165] audit: type=1400
audit(1505578476.590:03): apparmor="DENIED" operation="capable"
profile="libvirt-ab5c87f8-7085-be26-548e-d9433b84af89"
I see similar problems, however, I don't see any apparmor denys.
Actually, I'm totally puzzled by the effects I'm seeing...
I import a ZFS partition as p9 into a virtual machine which runs a
webserver. Everything worked fine under 14.04. Under 16.04 I see the
following problems:
No normal user
Adding to the list of virt-aa-helper extensions needed.
Yet I still look for someone to confirm that when the workaround is applied
(matching your custom dir) if then it is still apparmor that blocks you (and
with which message)?

Hmm,
it seems this fell through sorry for that.
With the workaround Serge suggested is the apparmor denial still just the same
e.g.:
apparmor="DENIED" operation="chown"
profile="libvirt-a3ede2b7-63d4-bcfb-8342-724f20a8cc48" name="/srv/video/"
pid=3060 comm="qemu-system-x86" requested_mask="w"
Running qemu/kvm as root, setting type to passthrough did not help also.

The workaround does not work for me either.

Hi,
a workaround should be to add
/srv/video/ w,
to /etc/apparmor.d/abstractions/libvirt-qemu.
For this to have regressed since 14.04 it seems qemu must have started
chowning the file where it didn't before. The correct fix is for
virt-aa-helper to detect these and add an exception when
Hi I have this problem now too (it worked before upgrading to xenial
from trusty). My share is /srv/video on the host and video in my home
folder on the host. My ls commands output
host:
drwxrwxr-x 7 micah users 4096 Apr 14 20:49 video/
guest:
drwxrwxr-x 7 micah users 4096 Apr 14 20:49
