Boot diagnostics
-
Boot diagnostics -> Screenshot
-
Boot diagnostics -> Serial log
-
Serial console: This is low level management interface that lets you connect directly to vms boot and system console, just like plugging a monitor and keyboard into a physical server in datacenter
- It operates below the network layer i.e. we can access the vm even if ssh/rdp is failing
- we can fix boot or kernel errors or network misconfigurations
- Azure ensure Boot Diagnostis are enabled
- Access serial console from help
- Ensure we have a user with password based access
AWS EC2 trouble shooting
- AWS also has support for viewing the screenshot, viewing logs and connecting to serial console as discussed above
