             Summary: infinite lease times for a Dynamic Host Configuration Protocol should be avoided (like the plague)
                 Key: CLOUDSTACK-8303
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8303
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
            Reporter: Ronald van Zantvoort


The edithosts script in the SystemVM's currently doles out DHCP leases with infinite validity.
Considering the D in DHCP is for 'Dynamic', and considering it might be useful to change the information in the lease every once in a while (such as resolvers, gateways & searches etc.), it's very bad practice to do this.

Currently, aside from one very exotic RFC, it's impossible to inform VM's of changing network conditions because they simply won't fetch new leases.

Please consider changing it to at max 1 week or something, or better: a configurable.
