Hi, FWIW, FYI, I've contributed completions for the commands part of libvirt to zsh upstream, here's a quick screenshot: $ virsh <TAB> zsh: do you wish to see all 222 possibilities (111 lines)? n $ virsh allocpages <TAB> --add --all --cellno --pagecount --pagesize $ virsh start <TAB> f23-test fedora-24-beta rhel-7-server $ virsh stop <TAB> f24-test rhel-6-server ubuntu-16.04 $ There's also support for the -c/--connect flag and selective completion support for the following (domains seen as an example above): + domains + interfaces + networks + devices + nwfilters + pools + secrets + snapshots + volumes Supported commands are: virsh virt-admin virt-host-validate virt-pki-validate virt-xml-validate Since virt-admin requires root/sudo, there are some additional security checks in zsh upstream to enable sudo for completions only by request. This will require the next zsh release. I've uploaded a version of these completions which uses sudo unconditionally to my fedorapeople.org page and it can be used by the adventurous already today (by placing it under /usr/share/zsh/*/functions/): https://myllynen.fedorapeople.org/_libvirt Cheers, -- Marko Myllynen
