Thanks to work from Johnny, linux 3.18.12 with all the x4c blktap goodness have been built and are now in the virt6-testing repo. I've also uploaded libvirt 1.2.15. As you may have seen earlier today, virt6-testing also includes an updated 4.4.2 package with the latest security update (XSA-133). The kernel has had some basic testing (by myself, Johnny, and another community member), but libvirt is at the moment untested, so caveat emptor. With such a large change, I want to leave both up for a few weeks before pushing them into the main repo. Please test them and report any errors you find. As a reminder, you can use the virt6-testing repo by putting the following file into /etc/yum.repos.d: [virt-testing] name=VirtSIG-\$releasever - Xen Testing baseurl=http://cbs.centos.org/repos/virt6-testing/\$basearch/os/ gpgcheck=0 enabled=0 For the adventurous, there are (as yet untested) kernel and xen packages in virt7-xen-44-candidate as well. I'll be pushing those to testing once I've actually had a chance to do set up my testing environment. Peace, -George
