Now with a single networking node (we called Virtual Router VM) with Dnsmasq, we can achieve creating 10,000 VMs within 23 minutes; and with a patched Dnsmasq based on your work of inotify, we can even improve the performance to 11 minutes! Dnsmasq is awesome! We can't archive such a good performance, without Dnsmasq. </div><div style="font-size:12.8000001907349px"><br></div><div style="font-size:12.8000001907349px"> We will continue working with Dnsmasq community closely to improve our project and tell you our thoughts about Dnsmasq. Your suggestions for our project are always welcome! Thank you.</div><div style="font-size:12.8000001907349px"><br></div><div style="font-size:12.8000001907349px"><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Feb 18, 2015 at 4:59 AM, Simon Kelley <span dir="ltr"><<a href="mailto:simon@thekelleys.org.uk" target="_blank">simon@thekelleys.org.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">-----BEGIN PGP SIGNED MESSAGE-----<br>

</span>Changing the dnsmasq configuration, specifically dhcp-host entries,<br>
won't affect any current DHCP leases, so if you want to end a DHCP<br>
lease early (maybe to re-use the address) then you'll need to call use<br>
dhcp_release. That can be before or after sending SIGHUP it doesn't<br>
matter.<br>

</span>My mistake sorry, I saw talk about VMs and assumed openstack. I'd be<br>
interested to hear more about the system you are working on, on or off<br>
list.<br>
<br>
<br>
If you need to have configuration deleted automatically when the file<br>
is deleted using inotify, I can look at doing that. It's significant<br>
extra complexity, so it makes sense to determine if it's needed first.<br>
<br>
<br>
Cheers,<br>
<br>
Simon.<br>
