[Bug 1249708] Re: Missing neutron-ovs-cleanup service

2013-12-11 Thread Jian Wen
I think this tool needs to be run on l3 nodes and dhcp nodes.
It should only be run when rebooting a node.
And it should finish the cleaning before l3 agent or dhcp agent starts.

In some environments, nova compute, l3 agent and dhcp agent are on the same 
node [1].
We need to make sure that the tool finishes the cleaning before nova compute 
starts.

It's kind of complicated. That's why I don't like the idea that using a 
upstart/init job to do the cleaning.
Maybe it's better that l3 agent and dhcp agent replug the ports themselves 
during starting.

[Bug 1197282] [NEW] install fails with apparmor disabled

2013-07-03 Thread Jian Wen
Public bug reported:

Boot a precise instance with  kernel option 'apparmor=0'
Install maas-dhcp
ubuntu@ubuntu:~$ sudo apt-get install -y maas-dhcp
Setting up maas-dhcp (1.2+bzr1373+dfsg-0ubuntu1~12.04.1) ...
Warning: unable to find a suitable fs in /proc/mounts, is it mounted?
Use --subdomainfs to override.
dpkg: error processing maas-dhcp (--configure):

dpkg: dependency problems prevent configuration of maas-dns:

  Package maas-dhcp is not configured yet.
dpkg: error processing maas-dns (--configure):

Looks like apparmor should not be called in 
/var/lib/dpkg/info/maas-dhcp.postinst
and /var/lib/dpkg/info/maas-dhcp.postrm when apparmor is disabled.


Workaround
Boot the machine with apparmor enabled.

[Bug 1197641] [NEW] fail to install maas-dhcp in a container

2013-07-03 Thread Jian Wen
Public bug reported:

As we can see from bug 978297. 
In precise, apparmor doesn't start in a  container. 
So in debian/maas-dhcp.postinst and debian/maas-dhcp.postinst, we should 
not call the apparmor_parser command in a container.

/bin/running-in-container is used in /etc/init.d/apparmor to find out if it is 
running in a container.
