Very cool! Something like that should be implemented as a virsh subcommand (but it would likely use xpath syntax since that's what libvirt uses internally). >> Though in this case I think finishing off virt-xml is the best way to go, >> I've >> just never managed to give it the final push: >> >> http://www.redhat.com/archives/virt-tools-list/2011-April/msg00159.html > > Nice too, but limited to only supported options. :( True, but support also comes with docs, --help discoverability, no need to know the XML syntax, and future proofing against XML changes. That said there is definitely a need for both tools.
