Technical Details

what runs on :8101

The LDoms migration daemon (ldmd) uses TCP port 8101 by default for communication between the source and destination control domains. Migration traffic uses SSL/TLS encryption and carries the state needed to move a guest domain; this is a service-to-service control-domain connection, not a guest-facing application protocol such as HTTP. The port is relevant when an administrator initiates a migration and should generally be reachable only between the participating systems.

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

security overview

Migration can transfer sensitive guest memory and state, so restrict this port to trusted control domains and the management network; it should not be exposed to the public internet. Encryption protects migration traffic in normal use, but an internet-reachable migration daemon still exposes a privileged virtualization control-plane service to probing and potential implementation vulnerabilities.
