I'm just about to release libguestfs 1.20. This appendix covers issues specific to Fedora 18.
Fedora 18 defaults to using the libvirt attach-method, meaning that libvirt is used to create and manage the libguestfs appliance. There are several benefits to this (see the full release notes). You can switch back to the ordinary method (directly running qemu) at any time by doing: export LIBGUESTFS_ATTACH_METHOD=appliance
There is a bug in libvirt (or perhaps libnl, or somewhere else) which causes libvirtd to segfault occasionally: https://bugzilla.redhat.com/show_bug.cgi?id=875741
You will need selinux-policy >= 3.11.1-63.fc18 and libvirt >= 0.10.2.1-3.fc18 in order to use SELinux in Enforcing mode giving you the full benefit of sVirt protection. I have tested this and it all works well for me, but please open bugs if you find any problems.
