Hi, At first glance on the logs, I could see below reasons for the start VM failures
management server logs: 2021-04-19 18:31:13,539 INFO [c.c.v.VirtualMachineManagerImpl] (Work-Job-Executor-46:ctx-7073f4ff job-28887/job-28888 ctx-70a0c6b3) (logid:e613b60b) Unable to start VM on Host[-1-Routing] due to Connection is closed agent logs: 2021-04-19 18:31:25,017 WARN [kvm.resource.LibvirtKvmAgentHook] (agentRequest-Handler-1:null) (logid:92f2a447) Groovy scripting engine is not initialized.

Also, you can do a quick KVM agent restart and see if it works "systemctl restart cloudstack-agent" Regards, Harikrishna ________________________________ From: Fariborz Navidan <mdvlinqu...@gmail.com> Sent: Tuesday, April 20, 2021 12:22 AM To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: Cannot start stopped VMs Hello, Today, I just updated SSL certificate and it failed re-deploying system VMs. Also, when I try to start a VM that is stopped, it fails with message: Unable to create deployment due to insufficient capacity. I couldn't find the reason from logs. I have uploaded partial management server and agent logs. https://www.r9host.com/log/management-server.log https://www.r9host.com/log/agent.log It is a mission critical issue for us. I would appreciate if you guys check the logs and let us know what we can do to fix this issue.
