Hi, On a Fedora 18, I try to launch a VM with QEMU-GlusterFS native integration. I have enable fedora-virt-preview repo, and gluster-alpha3 repo. Below the list of installed package : glusterfs-3.4.0-0.3.alpha3.fc18.x86_64 glusterfs-devel-3.4.0-0.3.alpha3.fc18.x86_64 glusterfs-fuse-3.4.0-0.3.alpha3.fc18.x86_64 glusterfs-server-3.4.0-0.3.alpha3.fc18.x86_64 ipxe-roms-qemu-20130103-2.git717279a.fc18.noarch libvirt-1.0.4-1.fc18.x86_64 libvirt-client-1.0.4-1.fc18.x86_64 libvirt-daemon-1.0.4-1.fc18.x86_64 libvirt-daemon-config-network-1.0.4-1.fc18.x86_64 libvirt-daemon-config-nwfilter-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-interface-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-libxl-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-lxc-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-network-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-nodedev-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-nwfilter-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-qemu-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-secret-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-storage-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-uml-1.0.4-1.fc18.x86_64 libvirt-daemon-driver-xen-1.0.4-1.fc18.x86_64 libvirt-python-1.0.4-1.fc18.x86_64 qemu-common-1.4.1-2.fc18.x86_64 qemu-img-1.4.1-2.fc18.x86_64 qemu-kvm-1.4.1-2.fc18.x86_64 qemu-system-arm-1.4.1-2.fc18.x86_64 qemu-system-x86-1.4.1-2.fc18.x86_64 I have recompiled Qemu with –enable-glusterfs .
