Hello, I've done a fresh install of cloudstack 4.11.3 on 2 ubuntu 18.04 servers (1 server hosts the management server , the other hosts a KVM host). I've configured the cloud using the wizard. Everything works fine except that I receive "internal server errors" when I stop the VMs . From the UI , the status stays as "stopping'; so the workaround is to go to the DB and set the status as "stopped". Expunging the VM results also in a internal server error too.
Looking at the management server logs, I can see these errors : 2019-07-16 22:49:59,967 DEBUG [o.a.c.n.t.BasicNetworkTopology] (AgentManager-Handler-2:null) (logid:) REMOVING DHCP ENTRY RULE
