[Libguestfs] Release notes appendix for libguestfs 1.20 on Debian Wheezy

I'm just about to release libguestfs 1.20. I want to cover some things that are different or won't work as well in Debian Wheezy. ** Most important ** Debian Wheezy ships with febootstrap 3.17. This is too old to run libguestfs 1.20 out of the box (febootstrap >= 3.20 required). However if you apply the attached patch to libguestfs, then it will work with the older febootstrap. virtio-scsi is not working properly in the older version of qemu that Debian Wheezy ships (qemu 1.1 is shipped, qemu >= 1.2 is required). For this reason I have added code to libguestfs which detects if you have qemu < 1.2 and forces virtio-blk. Unfortunately this means you don't get the benefits of virtio-scsi (see the main release notes). Because of lack of virtio-scsi and too old libvirt (libvirt 0.9.12 is shipped, libvirt >= 0.10.2 is required), the new libvirt attach-method will not work in Debian. See the release notes for what you'll miss out on. Of course the default (appliance) method works fine, and libvirt is not required. Even if newer libvirt and qemu where available in Debian, it seems unlikely that sVirt protection would work. This is partly because of the obvious fact that Debian doesn't use SELinux (by default). But mainly because we have made several changes to the SELinux policy in Fedora to support libguestfs with libvirt and sVirt. Also, although in theory AppArmor could implement sVirt (there is code in libvirt to do this) I have not even come close to testing this scenario. The tune2fs test is broken (in libguestfs). The easiest thing is just to skip it: export SKIP_TEST_TUNE2FS=1 'vfat' filesystem on Debian is somehow different from the same kernel filesystem on Fedora. I don't exactly know why but this breaks the test-charset-fidelity test. You can skip this by doing: export SKIP_TEST_CHARSET_FIDELITY=1 The IDE device either isn't emulated by Debian's KVM, or there is a missing driver in the Debian kernel, or for some other reason it doesn't work. I didn't look closely, but skipped the test by doing: export SKIP_TEST_RHBZ690819_SH=1 Disk labels (a new feature) don't work with Debian udev. Again, I did not investigate in depth. You can skip the test by doing: export SKIP_TEST_DISK_LABELS_PL=1 Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.
