Description of problem: Unable to start libvirt lxc domain a second time after shutdown/forced shutdown/reboot


Version: libvirt 1.1.2
patches:
[PATCH 1/3] Also store user & group ID 
[PATCH 2/3] Ensure system identity includes process start timevalues in virIdentity
[PATCH 3/3] Add support for using 3-arg pkcheck syntax for process


How reproducible:
Always

Steps to Reproduce:
For me, same problem with libvirt api or virt-manager.
Define domain, similar to this one (or create using virt-manager):

<domain type='lxc'>
  <name>test</name>
  <uuid>f14b9283-b0c5-be4a-d6a5-2ebbe74edcbb</uuid>
  <memory unit='KiB'>1048576</memory>
  <currentMemory unit='KiB'>1048576</currentMemory>
  <vcpu placement='static'>1</vcpu>
  <resource>
    <partition>/machine</partition>
  </resource>
  <os>
    <type arch='x86_64'>exe</type>
    <init>/sbin/init</init>
  </os>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/lib/libvirt/libvirt_lxc</emulator>
    <filesystem type='mount' accessmode='passthrough'>
      <source dir='/var/lib/libvirt/filesystems/test/root.copy'/>
      <target dir='/'/>
    </filesystem>
    <interface type='network'>
      <mac address='00:16:3e:bc:ae:b9'/>
      <source network='default'/>
      <target dev='veth0'/>
    </interface>
    <console type='pty'>
      <target type='lxc' port='0'/>
    </console>
  </devices>
  <seclabel type='none'/>
</domain>

Put a "full-blown distribution bootstrap" inside /var/lib/libvirt/filesystems/test/root.copy

Start domain for the first time. Everything works fine.
Shut down the machine ((Forced) Shutdown from libvirt, "halt" inside machine, doesn't matter)

Try to start domain again. 

Actual results:

You get an error message:
Unable to start Domain: Failed to connect socket to '/var/run/libvirt/lxc/test.sock': Connection refused.


Expected results:

Normal startup of the domain as like on the first time.

Additional info:

Rebooting the host machine somehow fixes the problem. I then can start the domain, but only one time (until the next host machine reboot).
