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]

Can you check if libvirtd service running on your KVM host? Also, you can do a 
quick KVM agent restart and see if it works "systemctl restart cloudstack-agent"

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/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.

Thanks.
