vsock notes

about vsocks

Vsocks are a means of providing socket communication (either stream or datagram) directly between VMs and their host operating system. The host and each VM have a 32 bit CID (Context IDentifier) and may connect or bind to a 32 bit port number. Ports < 1024 are privileged ports.

• Vsock communication between VMs does not seem to work.
• Only one vsock device per VM is supported.

## One line per log entry with merge graph
## (--decorate is implicit for newer git versions?):
#git log --graph --oneline --decorate

##                                                                             |
## Add --branches --remotes --tags --merges to see entries for all of the
## corresponding refs, not only commits (--all for all refs).

## Format output with --pretty=tformat:'<format>'
## Interesting placeholders for oneline <format>:
