THis has been known about for a long time, but it cannot be fixed because renaming the command will break any scripts currently using this functionality.
However, we could add a shadow command that used exactly the same implementation, but was named correctly. Then we would have both "virsh nodedev-dettach" and "virsh nodedev-detach", but newer users could use the correct spelling.
That will cause more trouble than it is worth, because then people will write scripts / docs using 'nodedev-detach' and they'll not be compatible with any existing deployment.
Well, we could certainly backport the right spelling to any production we ship, couldn't we? (I realize you can't *force* people to deploy errata, but...)
