Mikko, I guess you are right.
After I unplug my iPhone, cpu usage of upower goes down to near 0%.

Steps to verify the fix:

1. Copy the patched upstart configuration to /etc/init
2. Execute the following commands:

   sudo stop nova-compute
   sudo stop libvirt-bin

   sudo start nova-compute
   sleep 10
   sudo status nova-compute
   # nova-compute start/running, process 13692
   # It's up and running. No error log is appended in nova-compute.log.

[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.

The OVS cleanup utility introduces another bug that I think is important:

Maybe purging the ovs of devices created by quantum after

I managed to reproduce it by using a smaller disk for my devstack VM.

The  backtrace of libvirtd is attached.

Looks like it's related to

I guess I can reproduce the bug by  deleting and creating instances with
NWFilter configured forever in 4 processes. I will try when I back home.

[Bug 473389] Re: checksums does not match.

2013-07-10 Thread Jian Wen
Make sure the sha1sum of iso is OK by searching the value on Google

When it fails with "checksum does not match", do the following steps

Find out which one failed
cd $usbdrive_path
md5sum -c md5sum.txt 

Copy the mismatched file to you hard disk, check the checksum again.
If the checksum does not match, too.
Check the filesystem.
umount $usbdrive_path
sudo fsck.vfat -nVv /dev/sdb1 #adjust the path

Repair it
sudo fsck.vfat -a /dev/sdb1
I am not sure if the above command is the best command to repair the fs.

[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.
ubuntu@ubuntu-lxc-virtual-maas-0:~$ dpkg -S /bin/running-in-container

[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):
 subprocess installed post-installation script returned error exit status 1
dpkg: dependency problems prevent configuration of maas-dns:

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

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.
