andrijapanicsb commented on issue #3627: [do not merge] server: Do NOT cleanup dhcp and dns when stop a vm
URL: https://github.com/apache/cloudstack/pull/3627#issuecomment-540796870
In short - NOTHING IS CLEANED at all, whatsoever...
Test:
ENV built based from packages built from this PR (VMware 6.5u, CenOS7 mgmt) - clean install.
Created Isolated network (R21 in examples below)
Created Shared network (R22 in examples below)
Created a "vm1" (and some more VMs, but irrelevant) and joined vm1 to:
- Isolated network (default one) , IP 10.1.1.101
- Shared network (additional network), IP 1.1.1.4
While VM running, inside R21 (Isolated)

Identical results are for R22 (Shared network) - zero difference in grep results (not sharing, for brevity)
