On latest F18 with an F18 guest I can boot w/ cirrus fine, though there are some graphical issues:


Since there's been plenty of F18 changes in 2 months, closing as WORKSFORME. John, if you can still reproduce with latest bits, please the qemu command line (/var/log/libvirt/qemu/$vmname.log if you're using libvirt/virt-manager). And if you are using cirrus with an existing guest, or trying to install a new one.
