andrijapanicsb commented on issue #3627: server: Do NOT cleanup dhcp and dns when stop a vm URL: https://github.com/apache/cloudstack/pull/3627#issuecomment-557319517 @weizhouapache @rhtyd I think I see a bit of a problem with this one (somewhat edge case). VM1 has default network NET1 VM1 is attached to NET2 as an additional network - DNS and DHCP configs are created for this in the VR of NET2 (/etc/hosts and /etc/dhcphosts.txt We later detach VM1 from NET2 (and potentially never again attach it) - garbage is left forever in VR of NET2 (this consumes IP if nothing else). Can you think of any other consequence here? I see that when attaching AGAIN VM1 to NET2, a NEW config (new IP) is used in DNS and DHCP config, while the OLD IP is still present (in /etc/hosts and /etc/dhcphosts.txt) - so this will make issues for sure.
