Hi Corey,

Thanks for the fixing.

And I am using 'sudo adt-run neutron -U --apt-pocket=proposed --- qemu
adt-trusty-amd64-cloud.img -d -o /tmp/neutron/' for running the pkgtest.

2016-02-16 Thread Xiang Hui
Hello all,

After reproducing the test on my environment, the error is reported as:

The following packages have unmet dependencies:
 neutron-plugin-hyperv : Depends: neutron-common (= 1:2014.1.5-0ubuntu1) but 
1:2014.1.5-0ubuntu2 is to be installed
adt-run: & apt0t-hyperv-plugin:  - - - - - - - - - - stderr - - - - - - - - - -
E: Unable to correct problems, you have held broken packages.

It seems unrelated with the neutron fix in the patch but other
dependency problem.

Hi Serge, Brian,

Thanks for looking at it, could the auto package tests re-run again or
some other approach to identify the failure, since I can't see how this
simple fix can break  brocade-plugin showed in
http://autopkgtest.ubuntu.com/packages/n/neutron/trusty/armhf/, plus if
it has passed the -proposal which if running the neutron tests, it
should be work for -updates as well.

brocade-plugin   FAIL non-zero exit status 1

Thanks guys.

[Bug 1513367] [NEW] qemu-system-x86_64/kvm-spice failed to boot a vm with appmor enabled

2015-11-05 Thread Xiang Hui
Public bug reported:

This bug is seperate from bug
https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1384532 to focus
on the error.

I have been trying to redeploy the environment, for this time, the error
is not about kvm-spice, it is qemu-system-x86_64 got the same problem.
Due to /usr/bin/qemu-system-x86_64 is a bin file, I am not able to put
the strace there. And I don't know why suddenly /usr/bin/kvm-spice has
been replaced by /usr/bin/qemu-systerm-x86_64.

2015-11-05 15:36:15.491 DEBUG nova.compute.utils

+ The root cause is :

process will be respawned every 'respawn_interval' minutes due to get error 
output 'sudo: unable to resolve host juju-precise-machine-5' when running 
command 'sudo neutron-rootwrap /etc/neutron/rootwrap.conf ovsdb-client monitor 
Interface name,ofport --format=json', after several times the ovs db socket is 
reconnected for multiple times, however, some of them are not released well, 
and it goes to the maxim limit of socket number, which leads to connect to 
ovsdb server failed.
+ 
+ Currently, one possible fix in code is to add hostname to /etc/hosts
+ followed by 127.0.0.1 or localhost to avoid the error 'sudo: unable to
+ resolve host juju-precise-machine-5' in openvswitch charm.

  Workaround:
  restart openvswitch-switch
  
  But ovs-vsctl will get this error every several minutes, this caused
  neutron-plugin-openvswitch-agent keep reporting errors since ovs-vsctl
  is wrong.
