I changed the system to hup a while back. I was having the same problems.
At that time I never ran into the leases problem, but recently I did have
problem with it as well.
The workaround I'm testing right now is to

What is scripts/network/exdhcp/dnsmasq_edithosts.sh ?
I noticed that master is already patched to hup, but it's missing the
dhcp_release that dennis just put in a review for.

I'm not sure how we'd handle older versions if they don't have the
dhcp_release util, but how about this going forward?

The code to create system VMs is in the repo now. You should be able to
just make the change and / or submit a patch suggesting the change.
See
The set of packages installed is here:
http://s.apache.org/0c.
If you change it, it should get picked up in the next Jenkins build.
HOWEVER, note that the VMWare systemvm build is not fully automated (and
probably cannot be)

Something like this:

How do we go about requesting that dnsmasq-utils be installed on the new
system VM?

I think on new system VM edithosts should preemptively expire lease for the
passed ip and then sighup. That avoids complications in having to put in
separate calls to the router VM in each agent resource just to expire.

Ah.
I think this is a pretty big issue, especially in VPC, people could miss
getting an address if the router's service goes out. It may be the root
cause of CLOUDSTACK-2110. We are looking into it.

It does reconfigure the available leases for new IP allocations. It just
doesn't expire the leases it has already handed out.
If you replace the "service dnsmasq restart" in edithosts.sh with "kill -s
1" on the router VM, you'll start seeing these log messages when a VM is
destroyed and re-alloca
that's strange, because the dnsmasq man page explicitly calls out the
SIGHUP as a way to reconfigure DHCP hosts entries from a --dhcp-hostsfile
parameter. Or are these not the same thing?
