Jeffrey,  This is likely fixed in ocata-proposed and should be promoted to
ocata-updates soon after testing completes.

[openstack-dev] [kolla][ubuntu][libvirt] Is libvirt 2.5.0 in ubuntu cloud archive ocata repo bust

[Jeffrey Zhang]

Kolla deploy ubuntu gate is red now. here is the related bug[0].

libvirt failed to access the console.log file when booting instance. After
made some debugging, i got following.

# how console.log works
nova create a empty console.log with nova:nova ( this is another bug
workaround actually[1]), then libvirt ( running with root ) will change the
file owner to qemu process user/group ( configured by dynamic_ownership ).
Now qemu process can write logs into this file.

# what's wrong now
libvirt 2.5.0 stop change the file owner, then qemu/libvirt failed to write
logs into console.log file

# other test

* ubuntu + fallback libvirt 1.3.x works [2]
* ubuntu + libvirt 2.5.0 + chang the qemu process user/group to
  nova:nova works, too.[3]
* centos + libvirt 2.0.0 works, never saw such issue in centos.

# conclusion
I guess there are something wrong in libvirt 2.5.0 with dynamic_ownership
