Sorry, I meant to comment about this.

I figured in that case we can just let the libvirtd command fail, which should
report the lack of permissions. This saves us the hassle of having to report
'$BIN not found or lacks execute permissions.'

But I guess by that logic we can just drop the check and explicit error
reporting altogether: this stuff should really only error if the user screwed
up the install, so they can decode 'command not found' and 'permission denied'
errors. I'll send a new patch.
