If you’ve wanted to log into one of the cloudstack system vm’s but couldn’t find out how well this is your lucky day. Just ssh into the host with the systemvm on it. Get the “Link Local IP Address” from the CloudStack management portal under “Infrastructure” > “System VMs” > click the systemvm for more details. Once you have it use like this:
ssh -i /root/.ssh/id_rsa.cloud -p 3922 root@"Link Local IP Address"
That’s it. Easy right. Hope this helps.
