I asked ChatGPT and it gave detailed instructions for both Linux and Windows guests (you didn't say which one you have). They both involve minor edits to the XML file, but you should get the full answer yourself rather than me copy/pasting it. I've found AI tools to be generally useful for this kind of specific technical question. All they're doing is what you would do yourself in a web search, just much faster. poc -- _______________________________________________ users mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
