Ronald van Zantvoort created CLOUDSTACK-8303:
------------------------------------------------
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.
