qemu-ga: document vsock-listen in the man page

[PATCH] qemu-ga: document vsock-listen in the man page

Posted by Stefan Hajnoczi 5 years, 10 months ago

Although qemu-ga has supported vsock since 2016 it was not documented on
the man page.

Also add the socket address representation to the qga --help output.

Thanks to update it!
I updated the wiki page some months ago, adding an example, but I forgot to
check the most important man page and --help output.
