<br>
<br>does it possible assign IP when build VM? We have flat network setup
<br>with DHCP=false, but i have created start/end IP range so openstack
<br>assign IP when VM start.
<br>
<br>Yesterday one of my application crash and i was planing to rebuild VM
<br>with new OS, but problem is how do i assign existing IP? that IP is
<br>configured in all firewall,DNS, SSH key list etc.. it is total mess if
<br>i change IP :(
<br>
<br>can i grab old IP for that instance or just reserve that IP for that VM?
