Libvirt will need to expose an attribute that lets the user control whether to use this new option; how do we probe via QMP whether the new -boot strict=on command-line option is available?
Hi all,
How about add new info/query command?
(hmp) info strict-boot on
(qmp) {"execute": "query-strict-boot"} {"return": {"state": true}}
It might be not a good solution, I already updated qemu-options.hx, we can check help message to know if this new option is added or not.
Having libvirt probe the -help output is out of the question. We already declared that for qemu 1.3 and beyond, ALL command line behavior must ALSO be probe-able via QMP. I think Anthony had a trick for testing for existence of various command line options without needing to add a new query-strict-boot command, but I don't remember what that trick was.
