Hi,
I'm using VBox 5.1.8 on ubuntu 14.04.
I configured a NAT Netwrok type with DHCP for a VM which I regularly clone ("linked clone") from.
The cloned VMs are short lived, meaning they are destroyed after several minutes.
Everything works fine up until the last IP provided by the DHCP server (10.0.2.254).
Even though all the VMs are destroyed (even after 2 weeks), the DHCP doesn't assign IPs anymore to any of the new VMs cloned.
It seems like it doesn't return any of the destroyed IPs to the pool.
I couldn't find any way of making the DHCP server ignore the previous IPs and return them back to the pool of IPs.
I don't think it relates to the "lease time" since even after 2 weeks of no VMs, it still happens.
Any known issue about this?
Thanks,
Jonathan
