Erik Weber commented on CLOUDSTACK-8303:
----------------------------------------
I agree that it shouldn't be infinite.
> 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.
