LS, On upgrading our second production env to 4.2.1 we encountered a bug (at Schuberg Philis):
during the migration of firewall_rules_cidrs.source_cidr to network_acl_item.cidr. The source_cidrs are concatenated into a 255 width field. We are using cidr lists that are way longer. As a quick fix we can now set the size of the field to 2048. a quick test learns us that the field is truncated as it is saved in the db. I will enter a ticket with this info https://issues.apache.org/jira/browse/CLOUDSTACK-5886 4.3 and higher tests will folow, of course
