<div>
<p class="MsoNormal">Hi,<o:p></o:p></p>
<div>
<p class="MsoNormal">I'm using devstack to deploy stable/Kilo in my Xenserver.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I successfully deploy devstack. But I found that every time I restart it, devstack always run ./stack.sh to clear all my data and resintall all the components. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">So here comes the questions.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">1) Can I stop devstack from reinstalling after rebooting and just use the openstack installed successfully last time.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I've tried replacing the stack.sh with another blank shell script to stop it running. Then It didn't reinstall the services after rebooting. However, some services didn't start successfully.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">2) I found that devstack will exit if it is unable to connect the Internet when rebooting.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Is there any way I can reboot devstack successfully without connection to the Internet after I've install it successfully with connection to the Internet.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks in advance ! :)<o:p></o:p></p>
