I would use virBufferEscapeString here, even if by default the path should not contain characters needing escaping, I think it's safer.

Same thing here.

Overall the patch looks fine to me, +1 Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
