I have what might be a somewhat uncommon situation (cloning from a VM<br>
that has a valid lease), which I've been unable to eliminate a 10 second<br>
delay on.<br>
<br>
The scenario is:<br>
<br>
- I'm cloning linux containers/VMs in a very transient way. They come<br>
up and down frequently.<br>
- The new VM is cloned from a running VM which has a valid lease.<br>
- The new VM tries to renew the lease on the IP from the original VM,<br>
and gets NAK'd.<br>
- {Delay 10 seconds}<br>
- The new VM does a DHCPDISCOVER and quickly gets a valid IP.<br>
<br>
I modified the reboot timeout, and the initial-interval, but they didn't<br>
effect the 10 second delay. Is there another setting that would effect<br>
this? Or any other way to eliminate the delay?<br>

Have you monitored the client behavior in this state to see if it is the client which is waiting 10 seconds after the NAK?<br>
<br></blockquote><div><br></div><div>Yes, I used dhcpdump to monitor the requests, and I see the Client request, followed immediately by the server NAK. Then, it's silence for ~10s, and the client then sends a discover and the server responds appropriately.</div>
<div><br></div><div>So, it does seem to be only on the client side that the wait happens.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
