The gemspec is in the git repository. You should be able to clone git://libvirt.org/ruby-libvirt.git, then run "rake gem" to get a new gem.

actual registered block targets or rate limiting with iotune the burst iops.

ruby-libvirt aims to expose the libvirt API through ruby, not the virsh API. Sometimes virsh provides additional functionality on top of the libvirt API, which will not necessarily be implemented in ruby-libvirt. In this particular case, virsh domblklist parses virDomainGetXMLDesc() to output a list of block devices. virDomainGetXMLDesc() is supported by ruby-libvirt, but domblklist itself would not be. That being said, it should be fairly straightforward to implement it in ruby by first calling dom.xml_desc(), and then parsing the output with your favorite ruby XML parsing library.
